SPS8b. Newton's Laws of Motion Review

Slamming on the brakes in a moving car makes a passenger move forward against his or her seat belt because

• the passenger has the inertia to keep moving forward
• the passenger is being pushed by the seats of the car
• the passenger is better able to stop themselves in this manner
• the passenger has an equal and opposite force supporting their weight

For every _______ there is an equal and opposite ________. 

• reaction, action
• action, action
• reaction, reaction
• action, reaction

Why is it harder to push a van filled with bowling balls than it is to push a van with basketballs?

• The mass of the car is greater than the mass of the basketballs
• The mass of the bowling balls is greater than the mass of the basketballs
• The van with the basketballs is bigger than the van with the bowling balls
• It should be equally as hard to push the two vans
