Definition: Newton's Third Law of Motion states that "For every action, there is an equal and opposite reaction.

Consider the flying motion of birds. A bird flies by use of its wings. The wings of a bird push air downwards. Since forces result from mutual interations, the air must also be pushing the bird upwards. The size of the force on the air equals the size of the force on the bird; the direction of the force on the air (downwards) is opposite the direction of the force on the bird(upwards) For every action there is an equal(in size) and opposite(in direction) reaction.

These are pictures showing Newton's Third Law of Motion.

In our class, we were studying water bottle rockets. Before we launched the "rocket" we put different amounts of water in it. This would help it go up faster because it is the force pushing down and the water bottle rocket is going up.
