Simple Harmonic Motion & Hooke’s Law

Question 1

A body is said to be moving with simple harmonic motion if:

Answer 1

1) it’s acceleration is directly proportional to it’s distance from a fixed point on its path
2) it’s acceleration is always directed towards that point

Question 2

Hooke’s Law

Answer 2

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
