How does a swing move back and forth?

A swing moves back and forth due to the force of gravity and the momentum of the swing. Here’s a more detailed explanation:
When you pull a swing back, you are storing potential energy in the swing. This potential energy comes from lifting the swing against the force of gravity. When you let go of the swing, the potential energy is converted into kinetic energy as the swing starts moving downward.
As the swing moves downward, the kinetic energy causes it to gain momentum. This momentum carries the swing up on the other side, against the force of gravity. At the top of the swing, the kinetic energy is converted back into potential energy as the swing slows down and starts falling back down.
This cycle of converting potential energy to kinetic energy and back again is what causes the swing to move back and forth in an arc. The back-and-forth motion continues until friction and air resistance gradually slow the swing down over time.
The speed and arc height of the swing depends on factors like the length of the ropes, the weight of the swing, and how much force is applied to start the motion. But the basic physics behind the back-and-forth swing motion is this conversion between potential and kinetic energy.
