Answer 1

Why are the vibrations of a simple pendulum damped?

This is because the air drag and the friction at the support oppose the motion of the pendulum and dissipate its energy gradually. The pendulum is said to execute damped oscillations.

Answer 2

Explanation:

Explanation

For example, during oscillations of the bob of a simple pendulum, the friction of the pivot and the damping force due to the viscosity of air remain present due to which the amplitude of the oscillations of the bob goes on decreasing slowly and ultimately the bob stops.
