Newton’s 3rd Law of MotionPeriod 2: Page 65Periods 3-6: Page 66

Third Law of MotionFor every action, there is an equal and opposite reaction. You, on roller blades, push against a

wall.Object A: You Object B: Wall

Action: You apply a force on the wall. Reaction: The

wall applies the same force back on you.

Examples of the Third Law of Motion

You, on roller blades, push against a wall.

Your backward movement is the result of the wall pushing back against you.

Object A: You Object B: Wall

Examples of the Third Law of Motion

Flaming hot gases are pushed out the bottom of a rocket.

Object B: Rocket

Object A:Flaming hot gas Action: Gas is

pushed downward out of the rocket

Reaction: The rocket moves upward

Third Law of MotionExamples

The upward movement of the rocket is the result of the gases pushing downward from the rocket.

Third Law of MotionKey Points

The third law can be used to explain how a wing produces lift and a jet engine produces thrust.

On a wing, the air is pushed downward because of the wing’s unique shape (an airfoil). In reaction, the air pushes the wing upward.

A jet engine produces hot exhaust gases which flow out the back of the engine. In reaction, a thrusting force is produced in the opposite direction.
