Simple Harmonic Motion and Hooke's Law

Question 1

Hooke’s law

Answer 1

States that when an object is bent, stretched or compressed by a displacement s, the restoring force F is directly proportional to the displacement - provided the elastic limit is not exceeded

Question 2

A body is said to be in simple harmonic motion if:

Answer 2

Its acceleration is directly proportional to its distance from a fixed point on its path
Its acceleration is always directed towards that point
