Examine the image of a roller coaster. At what point on the track is the gravitational potential energy of the roller coaster car the greatest, and why?

• Point W; the roller coaster car has not yet gone down the ramp to convert stored potential energy to kinetic energy.

• Point X; the roller coaster car has not yet gone up the next ramp to convert stored potential energy to kinetic energy.

• Point Y; the roller coaster car will be at its highest point before converting potential energy to kinetic energy.

• Point Z; the roller coaster car will be at its lowest point before converting potential energy to kinetic energy.

A student observes a marble as it is rolled down a ramp with points R, S, and T marked. At what points does the marble have the least kinetic energy, and why?

• Points R and S; the marble is moving at point R and picks up speed at point S.

• Points R and T; the marble is not moving at point R and slows to a stop at point T.

• Points S and T; the marble picks up speed at point S and slows to a stop at point T.

• Points R, S, and T; the marble is not moving at all three points.

A class is measuring the amount of kinetic energy a toy car has as it travels down a ramp. Students observe that the toy car’s speed increases as it travels down the ramp. Which statement best describes the toy car’s kinetic energy as it travels down the ramp?

• The kinetic energy increases as potential energy decreases.

• The kinetic energy increases as speed decreases.

• The kinetic energy decreases as potential energy increases.

• The kinetic energy decreases as speed increases.
