Simple harmonic motion is a type of oscillation where the restoring force acting on an object is directly proportional to its displacement from the equilibrium position.
Springs: Springs are commonly used in mechanical systems to create oscillatory motion. They store potential energy when compressed or stretched and release it as kinetic energy during oscillations.
Pendulums: Pendulums are objects that can swing back and forth under the influence of gravity. They exhibit simple harmonic motion and are often used in clocks for timekeeping purposes.
