Answer 2

1. Simple harmonic motion is an oscillatory motion under a retarding force proportional to the amount of displacement from an equilibrium position.

2. An oscillation follows simple harmonic motion if it fulfils the following two rules: Acceleration is always in the opposite direction to the displacement from the equilibrium position. Acceleration is proportional to the displacement from the equilibrium position.

3. In physics, the restoring force is a force which acts to bring a body to its equilibrium position. The restoring force is a function only of position of the mass or particle, and it is always directed back toward the equilibrium position of the system. The restoring force is often referred to in simple harmonic motion.

4. The magnitude of the net force acting on an object is equal to the mass of the object multiplied by the acceleration of the object as shown in the formula below. If the net force acting on an object is zero, then the object is not accelerating and is in a state that we call equilibrium.
