Question

State the law of conservation of energy prove that the total mechanical energy of a body falling freely under gravity always remains conserved​

Answer 1

Answer:

In the case of a freely falling body, it is the mechanical energy of the system that is conserved. Mechanical energy (E) is the sum of the potential energy (U) and the kinetic energy (K) of the freely falling body. Therefore, E=K+U=constant.
