Damped and forced oscillations

Question

A simple pendulum oscillates in air with time period T and amplitude A. As the time passes

Moderate

A

T and A both decrease
B

T increases and A is constant
C

T increases and A decreases
D

T decreases and A is constant

Solution

Air friction causes the oscillating pendulum to damp. Then its amplitude decreases and time period increases finally comes to rest after some time
