Question

if a body falls from a height bounces from the ground and again go upwards with loss of its part of energy
(1) how will its potential energy change?
(2)how are various energy conversion take place ?​

Answer 1

initial energy = mgh

max height reached by body after one bounce = h ( assuming coefficient of restitution to be 1 )

so, there is no change in it's potential energy....

and firstly while falling it's potential energy is converted into kinetic energy and then after bouncing kinetic energy changes to potential energy.....

hope it is right....
