What is Hooke's Law?: Definition with Example

Hooks Law:  Robert Hooke, an English physicist (1635 - 1703 A.D) performed experiments on springs and found that the elongation (change in the length) produced in a body is proportional to the applied force or load. In 1676, he presented his law of elasticity called Hooke’s law.
Hooke's Law is also used in other everyday objects such as trampolines, where Hooke's Law is applied when the springs that hold up the center of the trampoline all stretch when a person jump on the trampoline.
