Question

show that the energy of freely falling object remains constant ​

Answer 1

Explanation:

It may be shown that in the absence of external frictional force the total mechanical energy of a body remains constant. ... 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.
