Question

A student is playing with a pendulum. He gives the ball a push and watches the ball as it swings. After a while, the ball stops swinging.Why does the ball stop swinging?

Answer 1

A pendulum ball stops swinging due to damping forces and the amplitude of the swing.

Step-by-step explanation:

When a pendulum ball stops swinging, it is mainly due to the presence of damping forces, such as air resistance and friction. These forces gradually reduce the energy of the pendulum, causing it to slow down and eventually come to a stop. Amplitude is the maximum displacement or distance a wave's oscillating particle moves from its equilibrium position during one complete cycle.

Another factor that can affect the swinging of a pendulum is the amplitude or the maximum displacement from the equilibrium position. For larger amplitudes, the period of a pendulum becomes longer, which means it takes more time for the pendulum to complete one full swing.
