Question

Q.2. Why does the oscillating bob eventually come to rest ?

what happens to its energy eventually ? is it a violation of

the law of conservation of energy? Discuss​

Answer 1

1)=The bob does not oscillate forever. It comes to rest because air resistance resists its motion. The pendulum loses its kinetic energy to overcome this friction and stops after some time. ... Hence, the total energy of the pendulum and the surrounding system remain conserved....

The law of conservation of energy is not violated because the energy lost by the pendulum to overcome friction is gained by its surroundings. Hence, the total energy of the pendulum and the surrounding system remain conserved....
