Amplify - Force & Motion Ch. 3

Three boats were moving across the surface of a lake. The gray and pink boats are a greater mass than the orange boat. Each boat was bumped by another boat. Which boat experienced the strongest force when hit? How do you know?

• The gray and pink boats because they are more massive, and all boats changed velocity by same amount.

• The pink boat - it's as massive as the gray boat and has the highest ending speed.

• All three - they all changed speed by the same amount.

• The gray boat - it takes more force to slow down an object than it takes to make it go faster.
