4.9 Newton's Laws of Motion

Newtons First Law

An object will remain at rest or at a constance velocity unless a net force acts on it.


Newtons Second Law
The acceleration of an object is proportional to the net force applied (F=ma)

Newtons Third Law
For every action there is always an equal and oposite reaction
