Question

(a) Name the type of energy possessed by a freely falling body of mass ‘m’ at the highest point 'h'.
(b) A freely falling object eventually stops on reaching the ground. What happens to its kinetic energy?

Answer 1

(a) Potential energy, P.E. is the energy possessed by a body of mass, m after reaching a height, h. it is given by, P.E. = mgh 

(b) K.E.of the object is converted into heat and sound energy.

Answer 2

a) Kinetic energy.
b)kinetic energy decreases.
