Question

state and prove low of conservation of energy in case of freely falling boy.



$plase \: give \: me \: answers$
​

Answer 1

Explanation:

Law of conservation of energy states that the energy of a system is always constant. 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. Therefore, E=K+U=constant.

Answer 2

Answer:

Law of conservation of energy states that the energy of a system is always constant. 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. Therefore, E-K+U=constant.
