The force of gravity makes a swing work. By leaning your body forward and backward as the swing passes the opposite direction, you cause the Center of Gravity (CG) to move slightly back from the center or slightly forward from the center. By doing this as momentum builds up, you can actually increase your swing arc. The length of the arc has an effect on the ability of the swinger to alter the CG. As the radius of the arc increases, so does the need for the offset of the lean to grow from the center of the arc as it would hang from dead center.

The primary force in a swing set is gravity, which acts to pull the swing downward. The tension force in the chains or ropes of the swing set counteracts gravity and allows the swing to move back and forth. The force applied by the person on the swing also contributes to its motion.
Tension in the chains of a swing pulls on the seat, allowing it to stay suspended in the air. When the swing is pushed or kicked, tension in the chains helps to keep the swing moving in a swinging motion. The tension changes as the swing moves, allowing for the back and forth motion.
