Question

state and prove law of conservation of energy for a free falling body​

Answer 1

Law of conservation of energy states that mass can neither be created or destroyed so free fall object also implies the same

Answer 2

Whenever energy changes from one form to another form to total amount of energy remains constant. suppose we have a ball of mass m and rise it to a height h above the ground the work done in raising the ball gives in a potential energy equal to m g h letters allow the ball to fall to fall downwards sofa sets height h above the grounddecreases does the potential energy also decreases what ask the call first its velocity v constantly increases and therefore its kinetic energy half MV square also increases as the ball falls more and more its potential energy is gradually converted into an equal amount of kinetic energy and the ball just reaches the ground its potential energy becomes zero and its kinetic energy becomes maximum at this stage all the potential energy converted into kinetic energy we conclude that potential energy of ball has been changed into an equal amount of kinetic energy there is no restriction of energy and total moment of energy remains constant this is an example of the conversion of energy during the free fall of a body.
