Question
Why does the motion of simple pendulum in due course stop while oscillating in air?
Solution
While the simple pendulum is oscillating in air, as a result of air friction, the energy of oscillator is dissipated into heat energy.
When whole of the energy of simple pendulum is dissipated, the simple pendulum stops oscillating.
When whole of the energy of simple pendulum is dissipated, the simple pendulum stops oscillating.
