Question

why does the oscillation of a simple pendulum eventually stop

Answer 1

A pendulum is an object hung from a fixed point that swings back and forth under the action of gravity. In the example of the playground swing, the swing is supported by chains that are attached to fixed points at the top of the swing set. When the swing is raised and released, it will move freely back and forth due to the force of gravity on it. The swing continues moving back and forth without any extra outside help until friction (between the air and the swing and between the chains and the attachment points) slows it down and eventually stops it.

Answer 2

Answer:

Basically, gravity causes the bob of a pendulum to move. Friction in air causes the the bob to eventually stop. If the force of friction is higher than the gravitational force, it will stop immediately.
