The restoring force is a force that acts on an object to bring it back towards its equilibrium position after being displaced.
Equilibrium Position: Equilibrium position refers to the point where there are no net forces acting on an object, resulting in zero acceleration.
Hooke's Law states that within elastic limits, the force exerted by a spring is directly proportional to its displacement from equilibrium.
Simple harmonic motion is a type of periodic motion where the restoring force is directly proportional to the displacement from equilibrium.
