16 Newton’s First Law of Motion An object at rest will remain at rest unless acted on by an unbalanced force.An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
17 What does this mean?This means that there is a natural tendency of objects to keep on doing what they're doing.All objects resist changes in their state of motion.In the absence of an unbalanced force, an object in motion will maintain this state of motion.
23 Newton’s Third Law of Motion For every action there is an equal and opposite re-action.
24 What does this mean?This means that for every force there is a reaction force that is equal in size, but opposite in direction.That is to say that whenever an object pushes another object it gets pushed back in the opposite direction equally hard.
