A pendulum swings because of the force of gravity. When the pendulum is released, gravity pulls on it and makes it swing downward. Gravity makes the pendulum increase its speed as it swings downward. When the pendulum starts to swing upward, the force of gravity slows the pendulum until it stops. Then the pendulum is pulled downward again and it swings in the other direction.
