What causes a pendulum to slow down and stop swinging?

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.

How can I make a pendulum clock run faster?

The clock can be made to go faster or slower by means of the nut at the bottom of the pendulum. Turning the front of the nut to the right speeds up the clock, and turning it to the left slows it down (in other words move the nut up to speed up, or down to slow down). Turn the nut only a small amount each time.
