Question

derivation of K.E.,power,conservation of energy

Answer 1

hey can u derive velocity or speed or distance. It is exact formulae which has been known.
K.E can be derived from eV.
Take a ball throw up when it reaches top the P.E is stored due to which it stops within a sec. it falls and P.E drops. just by this phenomena conservation of energy derived.
In reality there is no energy like K.E or P.E it is just an assumption like or phenomena.
