Question

show that the total energy of frelly falling object is same at every point




pz give early answer ​

Answer 1

We make use of the third equation of motion to obtain velocity of the body. Total energy at C = mgh … (3)It is clear from equations 1, 2 and 3 that the total energy of the body remains constant at every point. Thus, we conclude that law of conservation of energy holds good in the case of a freely falling body.
