Which toy boat(s) experienced the strongest force when it was bumped? How do you know?

• The blue toy boat experienced the strongest force because it takes a stronger force to slow something down than it takes to speed something up.

• The gray toy boat experienced the strongest force because it had the fastest ending speed.

• The orange and gray toy boats experienced the strongest forces because they both gained the same force as they sped up. The blue boat lost force, so it slowed down.

• All three toy boats experienced the same strength force because they changed speed by the same amount.

In which crash did the skateboard experience a stronger force? Why?

• The skateboard did not experience a force; only the shopping cart experienced a force in the crashes.

• Crash 2; the force on the cart was stronger in this crash, so the force on the skateboard was also stronger.

• The diagram doesn’t tell you anything about the force on the skateboard. It only gives information about the force on the shopping cart.

• The skateboard experienced the same force in both crashes. The shopping cart changed speed by the same amount in each crash, so the force on the skateboard was the same each time.
