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.

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?

(1 point)
Responses

The balls moved the cup the same distance.
The balls moved the cup the same distance.

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 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 lower mass moved the cup a greater distance.
The ball with the lower mass moved the cup a greater distance.
Question 2
b.  How did the mass of the ball impact the ball's kinetic energy?(1 point)
Responses

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.
An increase in mass caused a decrease in kinetic energy.

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.

GPT-4o mini · Answer

Here are the responses to each of your questions based on the principles of physics regarding mass and kinetic energy:

Question 1: How did mass affect the ability of each ball to move the cup? Response: The ball with the higher mass moved the cup a greater distance.

Question 2: How did the mass of the ball impact the ball's kinetic energy? Response: An increase in mass caused an increase in kinetic energy.

Question 3: What happened to the kinetic energy of the ball when it hit the cup? Response: Some of the energy was transferred to the cup.

These responses reflect the principles that kinetic energy (KE) is dependent on mass (KE = 1/2 mv²) and that when a moving object collides with another object, energy can be transferred or transformed during the collision.
