A _____ is a push or pull

At the MOMENT OF THE HIT, what is happening with the forces?

• They are equal and opposite

• The bat is exerting more force on the ball

• The ball is exerting more force on the bat

• There is no force

Which law explains how rockets are launched into space?

• Newton's First Law of Motion
• Newton's Second Law of Motion
• Newton's Third Law of Motion
• Newton's Fourth Law of Motion

Which law says that for every action there is an equal and opposite reaction?

• Newton's First Law of Motion
• Newton's Second Law of Motion
• Newton's Third Law of Motion
• Newton's Fourth Law of Motion

Who was the scientist who gave us the Laws of Motion?

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

The push or pull that acts on an object

• action
• acceleration
• force
• inertia

Forces always come in________

• waves

• groups

• pairs

When a cannon fires a cannonball we observe Newton's third law. Which force is the reaction force?

• The cannon moving forward

• The cannonball moving forward

• The cannon moving backward

• The cannonball moving backward

The man in the car slammed on his breaks. He then lunged forward in his seat. What is the reason for him lunging forward in his seat?

• friction

• gravity

• inertia
