Question

potential energy is relative.
*15) Prove that the kinetic energy of a freely falling
object on reaching the ground is nothing but
the transformation of its initial potential
energy
Ans. Let us look at the kinetic and potential energies​

Answer 1

Answer:

energy can never be created nor be destroyed so there is just a conversion of kinetic energy to potential energy

ke= 1/2 mv²

Pe=mgh

1/mv²+mgh = mechanical energy of that body

Answer 2
