A pendulum swinging, a see-saw moving up and down, and a rocking chair swaying back and forth are examples of things that go back and forth.
The periodic motion in a rocking chair is characterized by the back-and-forth swinging motion as the chair rocks on its curved legs. This motion is typically powered by the initial push or pull that sets the chair in motion, with the chair oscillating between two extreme positions. The frequency and amplitude of the rocking motion depend on factors such as the design of the chair, the force applied, and any frictional resistance.
Swinging chairs have been around for centuries and their exact inventor is unknown. However, their popularity soared in the 18th century when they were first introduced in gardens and parks as a form of relaxation and enjoyment.
Swinging back and forth on a swing involves periodic motion, specifically oscillatory motion. The motion repeats in a regular pattern as the swing moves back and forth around a fixed point.
