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

To determine how mass affected the ability of each ball to move the cup, the teacher conducted an experiment where she allowed two balls to roll freely down a ramp from the same height. One ball had a greater mass than the other. Each ball struck a cup at the bottom of the ramp. Now, to answer the question, we need to analyze the results of the experiment.
The correct answer is: "The ball with the higher mass moved the cup a greater distance."
Explanation:
The kinetic energy of an object is directly proportional to its mass. Kinetic energy is the energy of motion, and it depends on both mass and velocity. In this experiment, the balls had the same height and were released from rest, so their initial velocities were the same. Since their velocities were equal, the only variable affecting kinetic energy was mass.
According to the law of conservation of energy, the energy the balls had at the starting point (potential energy due to height) converted into kinetic energy as they rolled down the ramp. The ball with a greater mass had more kinetic energy compared to the ball with a lower mass.
When the balls struck the cup at the bottom of the ramp, their kinetic energy was transferred to the cup, causing it to move. Since the ball with a higher mass had more kinetic energy, it was able to transfer more energy to the cup, resulting in a greater cup motion.
Therefore, the correct answer is that the ball with the higher mass moved the cup a greater distance.
