Question

Prove that during the free fall energy remains conserved​

Answer 1

The body has moved a distance x from A. If the body reaches the position C. Thus we have seen that sum of potential and kinetic energy of freely falling body at all points remains same. Under the force of gravity, the mechanical energy of a body remains constant.

Answer 2

suppose a body at a point initially . then falls during the motion mechanical energy of the body is conserved , hence the total energy of the body is conserved during free fall.
