Third Law of Motion Examples

Newton's third law of motion states that every action has an equal and opposite reaction. Modern technology has used this law of motion to create many wonderful machines like jets and helicopters.

When jets take off, the engine creates a series of small explosions and pushes air backwards (the action). The action of air being pushed backwards propels the plane forwards (or the opposite of the direction of the action), thus enabling it to fly (the reaction).

If people in the Middle Ages had seen a helicopter, they would have probably attributed its unnatural movement to sorcery, but nowadays, we can attribute its flying capabilities to the same law that moves jets! When the helicopter blades are spinning, they push air downwards (the action), making the machine move shudder upwards (the reaction).
