The students want to see how changes to the design of the marble track will affect the energy of the marble. Part A One student wants to increase the potential energy of the marble at the starting position. Explain one way the students can adjust the track to increase the marble's potential energy. Describe the dimensions of any materials used to adjust the track. Which is the best description?

• Replace block Y and use a block with a greater height then block Y

• Replace block X and use a block with a greater height then block X

• Replace block Z and use a block with a greater height then block Z

• Replace block X and use a block with a lower height then block X

The students want to see how changes to the design of the marble track will affect the energy of the marble. Part A One student wants to increase the potential energy of the marble at the starting position. Explain one way the students can adjust the track to increase the marble's potential energy. Explain why the adjustment to the track would increase the marble's potential energy.

• Potential energy will increase with the higher new block replacing block Y

• Potential energy will increase with the higher new block replacing block Z

• Potential energy will increase with the higher new block replacing block X
