Because if energy conservation is NOT valid, then this would be equivalent to the laws of the Universe changing over time. The details of this relationship are complicated (some advanced math); if you know a lot of math, and are interested in this topic, do some reading on Noether's Theorem. If you don't know the advanced mathematics, you can still get a general overview.
coz we dnt want it 2 be made....u weirdos....we ain't as sad as u ppl...wanting to no...y energy cant b made...we hv a lyf...beta dan noin science....science is borin u idiots...hu Eva is teachin u dis stuf....must b a geek...GET A LYF
I don't know who told you it couldn't. It certainly can... in a sense. Einstein's most famous equation tells us that Energy can be converted into matter and vice versa, but it's possible for all of the matter/energy in a system to be in the form of energy at any given time.
PE = mgh = KE = 1/2mV2
gh = 1/2V2
================Who said I can not transfer potential energy to another form? Potential to kenetic energy shown mathematically.
No.because energy is a force of movement that can not be created.!
No, 100 years ago, scientists found out that energy cannot be made or destroyed.
Energy can only be changed from one form to another.
In order for all available energy to be converted to work, a reaction would have to be 100% efficient. No reaction is 100% efficient because some energy is lost as heat.
Why CAN'T it??? But that is exactly what the law of conservation of energy states! Anyway, it is one way to formulate it.
