Question

stall the law of conservation of energy show that when a body is falls from certain height and total mechanical energy remains conserved 5 marks questions​

Answer 1

Answer:

In other words, we can say that energy can neither be created nor destroyed. 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.
