Balloon Powered Car

What does Newton’s Third Law of Motion state?

• • Objects in motion remain in motion.

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

• • Force equals mass times acceleration.

• • Objects tend to stay at rest

In the balloon-powered car demonstration, what happens when the air is released from the balloon?

• • The balloon stays in place.

• • The car moves backward.

• • The air pushes the car forward, demonstrating an action-reaction force.

• • The car stays still.

What force propels the balloon-powered car forward?

• • Friction between the wheels and the surface.

• • The air being pushed out of the balloon.

• • The weight of the car.

• • Gravity pulling the car forward.

What is the action in the balloon-powered car setup?

• • The car pushing against the ground.

• • The air being released from the balloon.

• • The friction between the wheels.

• • The air moving inside the balloon

What is the reaction in the balloon-powered car setup?

• • The car being pulled down by gravity.

• The car moving forward as a result of the air pushing backward.

• • The air refilling the balloon.

• • The car staying still.

The balloon-powered car works because of Newton’s Third Law of Motion.

• True

• False

The car moves forward due to the friction between the wheels and the ground.

• True

• False
