Answer 2

Answer:

Total mechanical energy

Explanation:

when a body falls from a height H it has only potential energy. As it falls, The potential energy slowly gets converted into kinetic energy of the ball, which helps it to gain momentum. But the sum of the total potential energy and total kinetic energy of the ball remains unchanged. This sum is known as the Total mechanical energy.
