What is the name for the force that restores an oscillating body back towards its mean position?

Explanation:
The force that restores an oscillating body back towards its mean position is known as the restoring force. This force acts in the opposite direction to the displacement of the object from its equilibrium position. In the context of oscillatory motion, such as a mass on a spring or a pendulum, the restoring force is critical because it drives the oscillation by pulling or pushing the object back towards its mean position. In systems like a spring (according to Hooke's Law), the restoring force is directly proportional to the displacement and acts in the opposite direction, which is why it is termed “restoring.” This ensures that the oscillatory motion continues, as the restoring force acts every time the object moves away from its equilibrium position, creating a cycle of motion. Other forces mentioned, such as gravitational force and frictional force, play different roles in the dynamics of a system. Gravitational force is a constant force that acts downwards, influencing the motion but not specifically restoring it. Frictional force opposes motion, eventually leading to a stop rather than restoring motion. Centripetal force is relevant for circular motion, keeping an object moving in a circle, rather than restoring it to a mean position in oscillatory contexts. Thus, the
