Answer :
For oscillation in mechanical wave, restoring force acts in a direction opposite to direction of displacement.
- In physics, an object is said to be in equilibrium if there is no net force acting on the object. This can happen when the magnitude and direction of the forces acting on the object are perfectly balanced or simply because there are no forces acting on the object.
- Not all forces try to restore the object back to equilibrium, but forces that do so are called restoring forces.
- A restoring force is a force acting against the displacement in order to try and bring the system back to equilibrium.
- The restoring force is a function that depends on the position of an object or system. This type of force is responsible for generating oscillations and is necessary for an object to be in moving in simple harmonic motion.
- The restoring force is what causes the change in acceleration of an object in simple harmonic motion. A displacement from the equilibrium position results in the system storing potential energy.
