Question

Show that mechanical energy of a freely falling body justifies the law of conservation of mechanical energy

Answer 1

Answer:

Under the force of gravity, the mechanical energy of a body remains constant. Answer:As an object falls from rest ,its gravitational potential energy is converted to kinetic energy. So, According to law of conservation of energy,energy can neither be created,it can only be transformed from one form to another.

Answer 2

Answer:

the total mechanical energy of a body at a point during free fall is equal to the sum of kinetic energy and potential energy of the body at that point.
