Speed of light is 299,792,458 m/s (about 186,282.397 miles per second)
energy is a scalar physical quantity that is a property of objects and systems which is conserved by nature. Several different forms, such as kinetic, potential, thermal, electromagnetic, chemical, nuclear, and mass have been defined to explain all known natural phenomena.
that's what i got from wikipedia ^_^
PS:i bet you know all of this :P

But what IS energy? What composes it?
 
Sensible energy=the portion of the internal energy of a system associated with kinetic energies (molecular translation, rotation, and vibration; electron translation and spin; and nuclear spin) of the molecules.
Latent energy=the internal energy associated with the phase of a system.
Chemical energy=the internal energy associated with the different kinds of aggregration of atoms in matter.
Nuclear energy=the tremendous amount of energy associated with the strong bonds within the nucleus of the atom itself.
Energy interactions=those types of energies not stored in the system (e.g. heat transfer, mass transfer, and work), but which are recognized at the system boundary as they cross it, which represent gains or losses by a system during a process.
Thermal energy=the sum of sensible and latent forms of internal energy.

Is that helpful?
 
That's a very tricky question,but what i know is you can know what are the energy types composed of.
 
Are you trying to ask what energy is in general?

If that is what you are asking, all things can be used as energy. Energy can take form in any and every form mass. Everything has and is energy, no matter what it is.

Or were you asking something else?

If light enters the atmosphere of Earth, it slows. Once it leaves the atmosphere, it resumes its normal speed. Therefore, the temperature of the Sun has nothing to do with it.

Uhmm im not sure energy can do this but could it be diffusion? like gasses.
 
Yes, I am asking what energy is in general.

*EDIT*

But what forces it to accelerate upon leaving the atmosphere?

t accelerates cus theres no medium to slow it down -on earth the medium is air [My friend that im talking with said this, dosen't make sence ot me]
 
My defintion of energy is simple.

Energy equals anything and everything.

Books defintion-
A fundamental entity of nature that is transferred between parts of a system in the production of physical change within the system.

If light didn't travel at the speed of light, what would happen to "light". Anyone care to answer ;).

Nothing would happen...

Ive got another question, is everything that we see a reflection that light produces? or is something ACTUALLY that color not just the way that light reflects off it and we receive it?

the colours of the sun shine and some of the colours get refracted. which is why grass is green and the sky is blue.

Everything, a book is energy, yourself, my desk, my lighter, the light and anything else you can think of...

There are only a few types of energy-
Kinetic- associated with motion.
Radiant- electromagnetic waves.
Potential- the energy that a piece of matter has because of its position or nature or because of the arrangement of parts.
 
That answered the question "What does energy compose?"

My question was "What is energy composed of?"

That does answer the question, energy is anything that can convert or change a phyiscal form or move something, therefore you are energy, my book, myself and more... Whether or not the energy is active is different. Although everything is energy even if it has to be extracted in different ways.
 
You're explaining what energy is. I want to know what it's composed of. What are its constituent parts?

There are not parts or qualities of energy. Energy is transferable through things, it takes no shape or form of its own. So I am confused at what your asking?

Atoms are made of protons, neutrons, and electrons. Protons and neutrons can be broken down into their constituent parts. What can energy be broken down into?
