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

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
