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? (1 point) Responses The cup's motion was independent of the mass of the ball. The cup's motion was independent of the mass of the ball. The ball with the higher mass moved the cup a greater distance. The ball with the higher mass moved the cup a greater distance. The ball with the lower mass moved the cup a greater distance. The ball with the lower mass moved the cup a greater distance. The balls moved the cup the same distance.

How did the mass of the ball impact the ball's kinetic energy?(1 point) Responses A decrease in mass caused an increase in kinetic energy. A decrease in mass caused an increase in kinetic energy. Mass did not impact kinetic energy. Mass did not impact kinetic energy. An increase in mass caused an increase in kinetic energy. An increase in mass caused an increase in kinetic energy. An increase in mass caused a decrease in kinetic energy.
What happened to the kinetic energy of the ball when it hit the cup?(1 point) Responses Overall, kinetic energy was gained. Overall, kinetic energy was gained. All of the kinetic energy was kept by the ball. All of the kinetic energy was kept by the ball. Some of the energy was transferred to the cup. Some of the energy was transferred to the cup. Overall, kinetic energy was lost. Overall, kinetic energy was lost.
