Question

Show that the sum of kinetic and potential energy of a freely falling body is conserved.

Answer 1

Explanation:

Let a body of mass m falls from a point A, which is at a height h from the ground as shown in fig. 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.
