Question

In one part of this unit's sample work, we tested how mass impacts kinetic energy. First, the teacher allowed one ball to roll freely down a ramp. Then, from the same height on the ramp, she allowed a ball with greater mass to roll freely down the ramp. Each ball was allowed to strike a cup at the bottom of the ramp.
a. How did mass affect the ability of each ball to move the cup?
• The ball with the higher mass moved the cup a greater distance.
• The balls moved the cup the same distance.
• The ball with the lower mass moved the cup a greater distance.
•The cup's motion was independent of the mass of the ball.

Answer 1

• The ball with the higher mass moved the cup a greater distance.
