What happens if you just let the pendulum swing for awhile?

But what happens if we pull the pendulum bob up to one side and then release it? It will swing from side to side for a long time. At the height of each swing, in the instant when the bob is motionless between upswing and downswing, the system has all potential energy and no kinetic energy.

How do you make a pendulum that never stops?

Give it a tiny push once every swing (like in a grandfather clock). If that is not allowed, it will stop, but it can be kept swinging as long as possible as follows: Increasing the weight at the bottom end. Increasing the length. Why pendulum stops after some time? The pendulum bob stops oscillating after sometime due to the air resistance offered to it and due to the friction at the point of support.

Does the string that supports a pendulum do work on the bob as it wings to and fro does the force of gravity do work on the bob?

Answer: Yes, gravity does work on the bob when the direction of motion is not perpendicular to the direction of the force of gravity. People also ask does the string that supports a pendulum bob do work on the bob as it swings to and from? (b) As the pendulum bob swings, the force exerted by the string is radial (toward the pivot point) but the displacement is tangential, perpendicular to the force. We conclude that the work done on the bob by the string is zero.

What is the law of pendulum?

Also called pendulum law . a law, discovered by Galileo in 1602, that describes the regular, swinging motion of a pendulum by the action of gravity and acquired momentum. the theory holding that trends in culture, politics, etc., tend to swing back and forth between opposite extremes.
