What is the motion of a child on a swing called?

The motion of a child on a swing is called oscillatory motion. In this type of motion, the swing moves back and forth in a regular pattern, with the child swinging to one side and then returning to the other. This movement repeats itself in a rhythm, like a pendulum. The swing’s motion is an example of periodic motion because it follows a consistent cycle, going from one extreme to the other and back again.
