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.
