Accepted Answer

True

Answer

False

Question 12

What happens when two objects, such as a baseball and a bat, collide?

Accepted Answer

They hit each other with the same force in opposite directions.

Accepted Answer

Swimmer pushes on the water

Answer

the water pushes on the hand and the swimmer moves forward

Question 14

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

Accepted Answer

Sir Isaac Newton

Answer

Albert Einstein

Answer

Galileo Galilei

Answer

Aristotle

Question 15

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

Accepted Answer

The striking foot pushes backward against the ground. The friction with the ground provides an equal and opposite force forward.

Answer

As one leg moves backward, it provides an equal and opposite force for the other foot to move forward.

Answer

No acceleration takes place. Runners are always at a fixed velocity.

Answer

The runner's upper body quickly leans forward, causing the entire body to begin accelerating forward

Question 19

Which of the following best describes Newton's Third Law of Motion?

Accepted Answer

For every action, there is an equal and opposite reaction.

Answer

An object in motion stays in motion unless acted upon by an external force.

Answer

Force is equal to mass times acceleration.

Answer

Energy cannot be created or destroyed.
