"WebBasically, energy is something that is conserved in systems that look the same if you move them forward or backward in time. This is a consequence of something called Noether's theorem, that associates conserved quantities with symmetries. Another example is momentum, which is conserved when something is the same if you move it around. " - In a phrase how do physicists define “energy”
