Book toearth
Table tobook
Example 1
A horse harnessed to a cart exerts an equal and opposite force to the cart as it exerts a force against the ground.
Example 2
Space shuttle’s rocket boosters propel the orbiter into space by exerting an equal and opposite force to exhaust gasses.
Action: earth pulls on you
Reaction: you pull on earth
Action and Reaction on Different Masses
Consider you and the earth
Action: tire pushes on roadReaction: road pushes on tire
Action: rocket pushes on gases
Reaction: gases push on rocket
Concept Question 1
Why are we able to
walk?
Answer
We walk forward because when one foot pushes backward against the ground, the ground pushes forward on that foot.
Concept Question 2
What makes a car go forward?
Answer By Newton’s third
law, the ground pushes on the tires in the opposite direction, accelerating the car forward.
ReviewNewton’s Third Law:
For every action there is an equal and opposite reaction.
