(a) When a body of mass ‘m’ is thrown up with a velocity ‘v’, its kinetic
energy decreases progressively and after reaching a maximum height ‘h’, it
comes downwards. Explain the transformation of energy during the whole
journey of the body.
(b) Express the law of conservation of energy mathematically as followed in
this case

Answer. As object move upward is velocity will decrease due to deceleration by gravity. will decrease as it move upward. But its potential energy =mgH will increase as it move upward
