Oscillatory motion refers to the repetitive back-and-forth movement of an object around a central point or equilibrium position. This type of motion can be observed in various systems, such as a swinging pendulum, a vibrating spring, or the motion of a mass on a spring. The key characteristics of oscillatory motion include its amplitude, frequency, and period. In oscillatory motion, the object experiences restoring forces that bring it back to its equilibrium position. These forces are often proportional to the displacement from that position, as described by Hooke's Law. Common examples of oscillatory motion include the swinging of a swing, the vibrations of a guitar string, and the motion of a child on a seesaw.
