Question

How can you prove that the total energy remains constant at any point of movement of the ball from rest to the top​

Answer 1

Answer:

Mechanical energy is the sum of the potential and kinetic energies in a system. The principle of the conservation of mechanical energy states that the total mechanical energy in a system (i.e., the sum of the potential plus kinetic energies) remains constant as long as the only forces acting are conservative forces..
