Simple harmonic motion occurs when an object oscillates about a position known as the equilibrium point under the following conditions. A restoring force which always points toward the equilibrium point acts on the object. The force is proportional to the displacement of the object, and obeys the following law:
where x is the displacement and k is the spring constant or force constant.
Equation (1) is known as Hooke's Law.
Example:
Given that the spring constant is 2000N/m, find the force exerted on an object as it passes through a displacement of .01m.
