Use the table information to answer the question.

Two students drop an object into sand from a height of 1.5 meters. They record the depth of the hole made in the sand by each object. What is the most likely explanation for the results?

• Naveed's object had greater kinetic energy

• Maddie's object had a smaller width

• Maddie's object had a faster drop

• Naveed's object had less mass.

The image of a roller coaster is designed to show important information about potential and kinetic energy. One of these labeled pieces of information is correct. What information is wrong and why?

• The spot with the maximum kinetic energy should be on the lowest point on the roller coaster at the far left side on the bottom

• The roller coaster would only have kinetic energy at the point labeled gravitational potential energy and kinetic energy.

• The spot marked maximum gravitational potential energy should be on the lowest point at the far left side of the roller coaster

• The roller coaster would only have potential energy.

Four rivers have the same water flow over time but the fall from different heights to power hydroelectric dams. Which dam would provide the most hydroelectric power.

• dam D: fall height of 100 feet

• dam B: fall height of 75 feet

• dam A: fall height of 175 feet

• dam C: fall height of 135 feet

Why are the turbines for hydroelectric dams located far below the top of the dam?

• To ensure the water does not lose too much potential energy before reaching the turbines

• To allow the kinetic energy of the water to increase greatly before reaching the turbines

• To ensure the water does not lose too much kinetic energy before reaching the turbines

• To allow the potential energy of water to increase greatly before reaching the turbines
