What is energy? Some say its just a very useful quantity. But its also a very important concept. Its used everywhete in physics. Did we just some day randomly came up with something like F.S and declared it a very useful quantity or (1/2)mv^2 or other formulas. How did these ideads generate? I want its history. I read Feynman's explanation of energy.Read from what i could find. But still i do not understand.
