ENERGy!!!!!? i need to know what can make you reeeeeeally hyper, - any foods? - any drinks? - any energy drinks? (im looking mostly for answers with energy drinks) no alcohols or drugs please :D anything you could have at your house?

energy....? when going down a hill, is potential energy converted to kinetic energy or is that the other way around? and how does conservation of energy relate to roller coasters?

EnERGY?????? what can make you extremely HYPER... any foods...any drinks...energy drinks...ANYTHING???? please be specific for long term energy....more than 8 hours

Energy???? What on the earth is energy? Is it only what we are taught in physics class or is it anything more?

ENERGY!!!!!!!!!!!!!!!!!!!!!!!!? Are there any books that have some pretty good detai.s about energy drinks?? It is for my science project at school. thankies!!

ENERgY???? i am very sluggish right now. All ive had to eat today were some fries and coke. (i know, i dont usually eat like this :|) what food can give me aboost?

What is the energy conversion that occurs in cellular respiration? Chemical energy in glucose is converted to light energy. Light energy is converted to chemical energy in glucose. Energy in glucose is converted to packets of stored energy in the organism. Packets of stored energy are converted to chemical energy in glucose I need it for school, I'm in Virtual School and iI need it, Thanks.

What happen to heat energy after it is released to the atmosphere? According to the conservation of energy, energy is transformed into other forms of energy. In real cases, for example, in engines, not all chemical energy (from the fuel) is converted to kinetic energy (correct me if I'm wrong) because some of the input energy is dissipated as heat energy. So logically, the heat energy is released to the atmosphere. What happens to the heat energy after that?

How is energy conserved when a dropped object hits the ground? I know that when an object is held at a particular height above the Earth, it has a quantity of potential energy associated with it, but no kinetic energy. When the object is dropped, it loses potential energy and gains kinetic energy, thereby ensuring that energy is conserved. However, I've never understood what happens when the object finally strikes the ground; at this point, it has no potential and no kinetic energy. I'm sure some of it is released as heat and sound, but that can't account for all the energy, can it?

What energy changes take place when a ball that is falling through the air reaches its terminal velocity? I know that at terminal velocity, kinetic energy remains constant. I know that potential energy decreases because the height changes and air friction against the ball causing heat but I know that is minimal. I really need to know also, where does all that extra potential energy go because before terminal velocity, I would have said kinetic energy but because this is constant, where does the bulk of the potential energy go. Please correct me if I am wrong.

What energy exactly does photosynthesis extract from sunlight? Photosynthesis, the biological conversion from light energy to chemical energy... But I thought photons have zero mass (therefore zero energy?), so where is this energy coming from? Does it just refer to the extremely small energy that comes from a photon's momentum?

Is worldwide energy drilling and mining going at such a pace that will tank energy stocks in the near future? I look at a map of energy production around the world. There are so many mines, so many drill sites pumping oil, so much energy being extracted, competing with solar production etc. Is the energy sector bubbled at the top? It just doesn't make sense to me otherwise! Unbelieveable energy mining and drilling! Unbelievable!

What happens to black holes how much energy do they contain? What happens to all the energy that black holes consume? They must contain a massive amount of energy seeing that they eat up all the light and matter and energy that gets to close. What happens to this energy? Does the energy eventually cause the black hole to cease to exist? The reason a black hole is created is when the star starts to fuse iron and that takes energy. This in turn causes it to collapse in on it's self as it gobbles up the energy. If over millions or billions of years the Black Hole eats up enough energy will that energy destroy the singularity?

Where does the energy for gravity come from? According to the law of conservation of energy, energy is not created from nothing. It is either converted from mass or from other types of energy. In this case, where does the energy for gravity come from? For instance, the force pushing down the water in Niagara Falls is gravity, and we generate electricity from this energy. Where does this energy come from?

What is energy and how does it influence matter? I know it is possible that sub-atomic particles are made of energy-like things called quarks. According to my understanding of them they are more like energy than they are like matter. Unfortunately I have a very basic understanding of these particles and their relationship with energy. I have books about sub-atomic particles but they don't really talk about the influence energy has on matter. Anyone wanna give me a crash course on energy? How would you define it and its effect? Thanks in advance.

What happens to the kinetic energy when the ball lands in a sand trap? (Select all that apply.) The sand is deformed, i.e. its potential energy has been increased. The speed of the ball, and hence its kinetic energy, drops to zero. The speed of the ball increases as it converts kinetic into potential energy. The kinetic energy is consumed by the ball. Most of the kinetic energy is transferred to the sand. The kinetic energy is transferred to the air. Some energy is released as heat through friction. The ball expands due to a heat increase.

What is the difference between thermal and internal energy? According to many sources, internal energy is the kinetic and potential energies of molecules of a substance - combined. Some sources also say that thermal energy is that definition. However, I don't think that thermal energy is kinetic and potential energy combined. I know that heat transfer occurs between a region with higher temperature and a region with lower temperature, but it isn't necessarily the case with two regions of different internal energies. So that seems to imply to me that temperature is a measurement of thermal energy - so in that sense thermal energy is merely the average kinetic energy of molecules and as such, doesn't include the potential energy. Is that right? Thanks (:

What are the potential energy and the total energy at time tf? At time ti, the kinetic energy of a particle is 30.0 J and the potential energy of the system to which it belongs is 11.0 J. At some later time tf, the kinetic energy of the particle is 16.0 J. (a) If only conservative forces act on the particle, what are the potential energy and the total energy at time tf?

What is the difference between energy and power? a. Power is used to describe energy of light, while the term energy has a broader meaning. b. Power is the rate at which energy is used, so its units are a unit of energy divided by a unit of time c. There's no difference: Energy and power are different names for the same thing d. Power is measured in joules and energy is measured in watts.

If light and sound are energy waves, are they the same energy but on different wavelengths? We see light energy waves with our eyes, and hear sound energy waves with our ears. Light can be broken down into different wavelengths meaning we see different colours and can also be broken down into ultra violet and infra red; sound can be different wavelengths making different sounds and pitches. They are both energy waves. Are they the same energy broken down into different wavelengths resulting in us seeing that energy as light and sound?

What's the difference between Conventional, Conventional Alternatives, and Non-conventional energy alternative? I'm doing some research and have trouble distinguishing the difference between these three types of energy sources. So far, I have Conventional energy widely used/practical energy sources like oil, gas and coal. My assumption is that they're the primary 'standard' energy sources the world currently uses for their electricity and power since the industrial revolution. I'm having trouble with the next two energy sources.. Conventional Alternatives, I put that at energy sources that produce less environmental waste and could be used to replace conventional energy sources. An example would be biofuels being used to replace oil/gas for cars. I guess Nuclear power could go under this energy source as it could be used to replace coal in North America but places like France have 90% of their cities powered by Nuclear - would this mean it's a conventional energy source for France and a conventional alternative to North America? I don't know.. As for Non-conventional energy.. I put this at energy sources that produce the least amount of environmental waste but are completely unpractical to implement. My example would be hydrogen powered cars because there is no current infrastructure to support Hydrogen fuel gas stations if consumers were to buy them. I'm just purely guessing here - please share if you disagree or agree with my definition. Also If anybody knows what category other energy sources like wind, solar, and thermal energy belong to, I'll be super grateful.

What is the purpose of having energy drinks while working out? In the gym where I workout there are these chillers full of energy drinks like Gatorade and today there was this group handing out sample bottles of a new energy drink. My purpose of visiting the gym and working out is to burn energy and fat, not to take in more energy by way of energy drinks. The only beverage I drink while working out is water, so I keep my hydration levels up. I am confused why anyone would want to hit the gym to burn energy but then take in more energy while there.

How much more energy does a Plasma TV consumer compared to a LCD TV? How much more energy does a Plasma TV consumer compared to a LCD TV? Everyone says Plasma consumes more energy than a LCD, but by how much? Twice as much as a LCD? Newer versions of plasmas are now 'Energy Certified", does that mean they still consumer more energy than LCD, but overall, does not take that much compared to a traditional CRT TV?

Would you support a tax on energy to help global warming? If Obama wins in November 2008, and the Democratic Party continues to have control of the Congress I understand that they plan to put a tax on energy to pay for development of alternative energy and discourage use. Of course this could mean a tax on gasoline and your energy bills at home. The Democratic Party will insist that the money will be set aside for research and development of alternative energy. They say the taxes will encourage people to use less energy that will limit global warming. Would you support energy taxes for global warming?

How does nuclear fusion produce energy when it requires energy? How come atoms release energy when they are split, and also release energy when they are combined? Also, if a star's mass is the force that combines hydrogen atoms and creates all the elements (via gravity), doesn't all energy in the universe initially come from the force of gravity? Where does this energy come from?

How do I keep others energy from interfering with my own? I'm a hairdresser and am in very close proximity with many different people every day. I'm also very sensitive to other people's energies. I've noticed that this has began to effect me in a negative way because I bring all of this extra energy home with me and now I'm beginning to have problems sleeping and many other things that are effecting my every day life. SO my question is how can I keep others energies from interfering with my own energy, or how can I release this energy once I'm done with work?

So if this is the case, what happens to all of the energy stored inside, say, a person, if they were to die? Think about it, there's all sorts of like, emotional energy, it takes energy for all of the brain processes and such to occur, what happens to it all when the person dies? Could that be what a "soul" is?

How much energy is needed to raise the ocean's temperature? Where could that energy be found? You all say it would take more energy to cool the ocean and less energy to heat it. How does that work out?

How much energy is there in tidal power? I think the answer is a lot, but it is not infinate. Tides are caused by the moons gravitational effect on the earths oceans, but equally the oceans have a gravitational effect on the moon. This is slowing down the moon at a very very tiny rate. If we make use of tidal energy, then we slow down the flow of water, therefore increase the rate at which the moon's orbit is being slowed, by an almost infinatesimal amount. Anyone got an estimate for the numbers? Presumably the total energy available is the kinetic energy of the moon: 1/2m(v squared), where m is the mass of the moon, and v is it's velocity. But if the moon slows too much, will it's orbit not decay? How slow can it go before we need to panic? Don't get me wrong; I think tidal power is a great idea, this is a question of curiosity, akin to "when will the sun run out of fuel?" And yes the tides are slowing the moon. Inertia means that the main mass of the oceans is slightly behind the moon, and therefore pulls it back slightly. No idea of the numbers, something like 1 sec/10 million years? Maybe much less.

How much energy is used by the internet servers and telecomunications infrastructure to distribute SPAM? Every internet server or router need processor time to deliver any e-mail to it's correspondence Inbox. Microprocessors needs energy to execute it's instructions. Much of that energy came from oil. Overheating the planet. If we know the amount of energy the SPAM is wasting it could lead to harder penalties to those who use the Internet for that purpose.

Does taking energy from the zero point field or quantum vacuum violate the 1st law of thermodynamics? The first law states that "energy cannot be created or destroyed". Does taking energy from other dimensions really imply "creation", or just another way to obtain energy? Does it boil down to a violation because the extra dimensions have not been proven yet? Therefore, it "could" be a violation of the law?

How is wind energy going to create jobs? Not including the green jobs the free market has already taken into account. Wind energy costs 25% more than coal. In essence our energy productivity will go down by 25%. Whenever has productivity going down created jobs? Do not give me the foreign oil, the only time foreign oil is used in energy production is for peeker plants. Wind can not replace that. As an engineer I like the idea of power and all kinds of power. Also as an engineer I can not see a more expensive means creating jobs. The 25% more espensive is from my Mechanical ENgineering hand book. One coal generator vs. about 10,000 for wind for the same power. where to begin. I am an engineer. We wast more energy at night than we currently or probale ever will get from wind. If you borrow money to put in a plant, the building of the plant is a net zero jobs. As jobs are eliminated from other areas as you pay that back. Wind will take jobs away from other industries, raise your monthly rate, taking jobs away from other areas. I never said I was against wind (although we should focus on storage first) I just asked how it would create jobs. We can still make coal and Nuclear cheaper as well. It was not that long ago the guy designed the new hopper (funny shaped) that prevented cloggs. Thunder B, I have evidence from several engineering manual. The link ou produced neglects the energy wasted due to the fact the wind does not blow. If wind was cheaper it would go in under private investment. And T BOONE pickens would not need money to get it going. qris, Productivity decreasing does not create jobs. It may increase the job for that industry, but that means it must cost more and decrease jobs elsewhere. If you it takes a plumber 2X as long as one, you will be out more on plumbing and less on other things.

How can both nuclear fission and nuclear fusion release energy? Coming from a chemistry point of view, we are familiar with the concept that making bonds requires energy, and breaking bonds releases energy. So, it follows that fusion should require energy, and fission release energy. However, from a nuclear point of view we know that they both release energy. Anyone care to explain this to me? I have an exam tomorrow!!!!! The answer has to incorporate: -Binding energy per nucleon -Iron being the most stable element because of its binding energy per nucleon -driving force of nuclear reactors.

What is the difference between standard gibbs free energy change and gibbs free energy change? I am confused between standard gibbs free energy change and gibbs free energy change. Aren't both the change in gibbs free energy of the system when reactants are converted completely, or 100 %, to products? Why does the change in gibbs free energy of the reaction change as the reactioin progresses, but the standard gibbs free energy change is the same no matter what. I need a qualitative explanation more than a quantitative one. Thanks!

Does my energy bill stay the same regardless of the amount of bulbs I have? I just moved into a new apartment and I noticed that 2 of the light fixtures are capable of holding 2 bulbs but each only have 1 bulb in. Will I still be paying the same amount in my energy bill whether I have 1 bulb or 2 bulbs in the fixture? I don't know if the amount I pay is based off whether there's a bulb that is actually receiving the energy. I hope you can understand what I'm trying to say because I don't know if I asked it clearly. Thanks so much.

Hint: The latent heat of vaporization is 540 kcal/kg for water. Please use only the heat of vaporization, and not the energy required to raise the temperature to 100°C.

How much energy does an energy saving bulb use to start up? I have been told, by a friend, that an energy saving lightbulb usues 15 mins worth of electricity to start - getting up to temperature etc. So if only going out for 10 mins is it better to leave it running?

What are your ideas on how to create stable energy re-utilization systems? For instance, take the motor vehicle as an example. We use gas to derive energy to turn the wheels. The wheels expend some of their energy as heat produced by friction with the road. Is there some way to recapture the heat produced by the tire and reconvert it to energy that can be used again by the vehicle to propel itself. How about the heat form the motor? The EMI emissions from the electronics? Don't stop at just a motor vehicle. How can we recapture energy created by the various methods it takes to produce various consumables and reuse that energy perpetually instead of releasing it into the environment? The true ideal would be to have items that can be initially powered by a starting power source and then have them recapture maximum expended energy and feed it back into the system being used ( or fed into other systems for reuse). Can you think of ways to do this? What would they be? How about cooking stoves, laundry dryers, personal computers? Could it be done with those items? Sometimes people have great ideas and just would like someone to make them happen. Hopefully we have enough of those people to really make things happen.

How much potential energy does the water hold? If a dam holds 108 Kg of water above the ground 1000m below. How much potential energy does the water hold? If the transfer between Potential energy to kinetic energy is 90% due to friction and the turbine can convert 10% of the kinetic energy to useful electric energy how much energy can we get out of the water? Can someone help me with his problem? Thanks so much!

How can you tell if a light fitting takes only energy efficient bulbs when doing a building survey? I conduct Building Surveys with regard to new Part L regulations and Energy ratings. The requirements describe the use of energy efficient fittings as opposed to energy bulbs. The logic being that energy efficient fittings can't be used with non efficient bulbs. However there are so many types of fittings now and to be designed that I find it hard to tell from a distance which type they are. Any tips?

How does energy move in chemical reactions? In chemistry, I learned that it takes energy to break bonds (energy is absorbed) and that energy is released when bonds are formed. In biology, I learned that energy is released when bonds are broken and that energy is stored (absorbed) when bonds are formed. How can these two facts both be true at the same time? How are these facts related? Please answer not only how energy is transferred when bonds are broken, but also when bonds are formed. Thank you for any help.

What is the source of the energy released in nuclear reactions? What is the source of the energy released in nuclear reactions The conversion of nuclear kinetic energy to particle potential energy. Heat released during the radioactive decay process. The conversion of mass to energy. The binding of orbital electrons to the nuclear protons.

What happens to the energy of a raindrop as it falls? I understand that when a raindrop is high up it has potential energy. When it moves it has Kinetic energy. What exactly happens to the energy as it falls, than hits the ground? PLEASE answer I need help!!!!! So it still has Potential energy as it falls?

What happens to the energy stored within humans when they die? I've heard that energy cannot be created nor destroyed. What happens to the energy within each of us once we die? Where does it go?

What are different ways I could save energy in my home? What are different ways I could save energy in my home? Here's what I do now to conserve energy: -I turn the heat off before I leave the house -I minimize the degree to which I do laundry -My room has one energy efficient (this is the spiral one, right?) bulb -My lights are off when I don't use them Yet my bill is still extremely high. What else do I need to do or what else can I do that's not on the list? Cheers.

How much energy does a plug-in radiator use? My bedroom upstairs is a converted attic. No heat, no air. So, I use a plug-in radiator to heat the space. It gets toasty in about 2 hours...but how much energy is it using? Are plug-in radiators energy hogs?

What are some energy saving tips for a rental property? I am looking to start making my home a little more greener. As i live in a rental property and can not make major changes to the home.So i am looking for energy saving tips.Just to start out with.

What happens to the energy shells of an ionized atom? When an atom is ionized, the electron transfer to another atom, eg the outershell electron if Na goes to the outershell of Cl and it becomes salt. Does the energy shell from where the electron of Na was dissappears? What happens to that energy shell? Does that mean that Na is left with only 2 energy shells?

What competition would a store that sold energy drinks have? Shoe stores such as Payless have a lot of competition such as Aldo and other shoe stores. But a store that sold flowers wouldn't have as much competition because there aren't that many stores that sell flowers. What about an energy drinks store? Well actually it sells energy drinks, sports drinks, energy bars and whatever gives you an energy boost. What competition would it have? Also why would a store like that succeed. Example: energy drinks and sports drinks are a growing trend so many people buy them. Any other ideas?

How do the energy differences between the higher energy levels of an atom compare with the energy differences ? How do the energy differences between the higher energy levels of an atom compare with the energy differences between the lower energy levels of the atom? a. There is no significant difference in the magnitudes of these differences. b. They are smaller in magnitude than those between lower energy levels. c. No answer can be determined from the information given. d. They are greater in magnitude than those between lower energy levels.

What is energy save mode do when selected on an air conditioner? I have a Sharp 10000 BTU air conditioner that i bought used. I don't have the manuel for it so i dont know what it does. So does setting the air conditioner on energy save mode really save energy? And how does it work? Also it is 97 degrees today and VERY humid. So what temperature do you think i should set it as to be comfortable and save energy?

What Percent of Energy from Gasoline is Actually Used to Move the Car? I've heard that only less than 30% of the energy released from burning gas in a car is used to move the car and the rest is released as heat and other forms of energy. Forgot where I've heard this and I cannot find anything about this on the internet. Can anyone confirm this and possibly provide a source?

How much energy is contained in the average human? I don't know if I am using the right terminology, but I would like to know how much pure energy is contained in the average human? And there are 2 sub questions. Consider that a person weighing 150 pounds is exploded in a nuclear reaction somehow, as if the person were a nuclear bomb. How large a blast would you get? Would we simply use Einsteins formula e=mc squared? Or if we considered the energy released slowly like in a nuclear power plant, how much electricity would be produced by burning all the nuclear material in the average human? I hope I have asked this in a way that makes sense.

How do you turn elastic energy into kinetic energy?
