Define Newton's three laws
1st Law - a body will move with constant velocity or remain at rest unless acted on by a resultant force
2nd Law - F = ma. The rate of change of momentum of an object is equal to the resultant force and it acts in the same direction as the resultant force.
3rd Law - for every action there is an equal and opposite reaction.
