Explain Newton's 3 Laws
1. An object at rest will stay at rest and an object in motion will stay in motion with the same direction and the same speed unless acted upon by an unbalanced force.
2. The greater the mass of an object, the more force it will take to accelerate the object.
3. For every ACTION there is an EQUAL and OPPOSITE REACTION.
