Newton's third law

Newton's Third Law States...

• Objects in motion stay in motion and objects at rest stay at rest
• Force is equal to mass times acceleration
• For each action there is an equal and opposite reaction

An archer shoots an arrow. The action force is the bowstring against the arrow, the reaction force is...

• Air resistance against the bow
• the arrow's push against the bowstring
• the grip of the archer's hand on the bow

A player throws a ball. The action force is the player impact on the ball. The reaction force is...

• The force of the ball impact on the player
• The force of the grip of the ball
• The celebration the player is thinking of

A baseball player bats a ball with a force of 1,000 N. The ball exerts a reaction force (without any additional forces action on it) against the bat of...

• Less than 1, 000 N
• 1,000 N
• More than 1,000 N

Newton's Third Law is also known as...

• The Law of Inertia

• The Law of Acceleration

• The Law of Conservation of Momentum (Force Pairs)

According to Newton's third law forces come in pairs?

• True
• False

Which best explains why we are able to accelerate forward when starting to run?

• As one leg moves backward, it provides an equal and opposite force for the other foot to move forward.
• No acceleration takes place. Runners are always at a fixed velocity.
• The striking foot pushes backward against the ground. The friction with the ground provides an equal and opposite force forward.
• The runner's upper body quickly leans forward, causing the entire body to begin accelerating forward

When a large truck pushes a small car with a given force, the small car is applying an equal and opposite force on the truck.
