Describe all three of Newton's laws of motion
1. An object in motion stays in motion and an object at rest stays at rest unless acted upon by an unbalanced force
2. An object's acceleration depends on two factors, the amount of force applied to the object, and the objects mass. Otherwise known as F=MxA
3. Forces always act in pairs, every action has an equal and opposite reaction
