We all know there are 2 kinds of energy....?

Assuming the spring doesn't release that bit of its potential energy as kinetic energy by decompressing as it falls, it will be released as kinetic energy as the pieces of the disintegrating spring are forced apart due to the stress placed on the object and the action of the acid weakening its structure (there's no such thing as instantaneous disintegration... even if it only takes a millionth of a second, it still took some time to happen).\n\nBeyond that, quite a bit more chemical energy will be released as the acid oxidizes the metal in the spring and causes it to disintegrate.

Dark energy! Mwahahaha! Honestly, They probably use the same kind of energy as the stores around them (I assume this Hot Topic is in a mall).

its some type of energy thing for some

There are only two entities in the Universe, one is Consciousness and the other is Energy...but this energy too is self conscious\n\nIn us our body, mind, intelliegence and ego all are creation of the Energy....the Soul in us is pure consciousness and this soul is common to all.

I believe that we put energy into the world, not in an airy fairy way, but actual magnetic energy and the influence we have on others. \n this effect has not been properly researched by science\n Magic is what science hasn't explained yet. \nI believe that some people intentionally put bad energy into the world. \n ergo\nblack magic exists

yes you are right.. there are two sets of electrons

maybe a little bit of both..:D

Energy that enters the system from the surroundings.

It's two.  Energy goes as the square of amplitude.

You should re-ask.  Do you mean strength or heat or both?  We also produce electricity and build chemicals that store energy.  You need to define output better.

No one knows exactly.  It's interchangeable with matter, but no one knows exactly what matter is either.  We can describe properties of matter and energy with reference to each other, but we can't really objectively understand what they are.

I am going to take a guess and say the moon.\n\nNo, I am kidding, it's the Sun\n\nSolar energy can be converted in to electricity and heat.

both r developing contries.......both has enormous potential in the realm of energy.it's high time to put aside the differences and get moving.........

joules is energy...im dumb

A pendulum demonstrates the transfer of potential energy to kenitic energy.\n\nA light bulb demonstrates the transfer of electrical energy to light and heat.

Yeah man...light is one of the most energetic forms that we witness. Light actually has many types of energy, just like most other things. \n\n1) Photons of light (of a suitable frequency are capable of imparting enough momentum to an electron in a metal so that the electron leaves the metal's surface. This is known as the photoelectric effect and the credit for it's knowledge goes to Mr.Einstein.\n\n2) Light has heat energy, and therefore thermodynamic value. You'll see that if you stand in the sun too long, you will be hot. \n\n3) The thermodynamic energy of light causes photochemical reactions, such as the radicalisation of halogen atoms, or the redox reactions of alkyl halides. \n\nI cannot be too sure of my satisfaction quotient with this answer because your question overlays so many fundamental concepts of light. For example, you wouldn't ask a rolling ball, "Excuse me sir, but how much energy do you really have?" The ball will snicker because you have not specified WHAT KIND OF ENERGY you want from the ball. Now, if you were to ask, "Excuse me sir, what is your KINETIC energy?", the ball would happily answer that it would be half of its mass multiplied by the square of its velocity. \n\nOne of the kinds of energy does involve a mass parameter and that would be the photoelectrical energy of light. This energy functions on the sound premise that linear and angular momentum are conserved, and since light has dual (mass-wave) nature, this kind of energy does involve mass. \n\nWe know that the energy of a photon of frequency v is E=hv where h is Planck's constant. We also know that the energy of a photon in relation to its mass is E=mc^2. THus we can say:\n\nmc^2 = hv.\n\nAll right, here is a clear answer, which I just realized. \n\nOne photon of light has the above mentioned amount of energy, and therefore a ray of light will have the energy of how many ever photons are in the ray of light. \n\nSo for n photons, energy of the ray of light is nhv. \n\nNow THIS nhv can be CONVERTED into all of the forms mentioned above. Light has energy which is capable of doing different kinds of work. \n\nForgive me for the error of thinking that light has different forms of energy. It has one form of energy which can be CONVERTED into different forms of energy. Phew....\n\nI really must thank you as this was a learning process for me too.\n\nAyerhs.

Alternative forms of energy, some which can be used today. Solar, Wind, Water etc.
