Question :- Pendulum after some time becomes slow in motion and finally stops due to ?

Answer 1

Hey !

        When the body is made to oscillate, some kind of frictional force is present like friction because of air. This frictional force opposes the motion of oscillating body, when it is oscillating from equilibrium position or it returns towards the equilibrium position, therefore the energy given to the oscillating body in the initial displacement which is converted slowly but continuously into heat in doing work against friction.

                Because of this energy dissipation the amplitude of oscillation goes on decreasing and finally stops.

Good luck !
