SUMMARY
A pendulum will eventually stop moving due to friction, as demonstrated by the example of an American flag swinging in a vacuum. In a complete vacuum with no friction, the pendulum would theoretically swing indefinitely. However, in real-world conditions, the fibers and threads of the flag create enough friction to dampen its movements over time, leading to a complete stop.
