Question

Show that the total mechanical energy of a freely falling body under gravity is conserved.​

Answer 1

During the fall, the body is at a position B. The body has moved a distance x from A. ... 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.

this is your answer hope it helps you
