Multiple Choice

Mary throws a tennis ball into the air. It rises, stops momentarily when it reaches its greatest height, and then falls back to the ground. At what point does kinetic energy converted to potential energy?

• When the tennis ball is rising.

• When the tennis ball is falling.

• Just after the tennis ball hits the ground.

• While the tennis ball is at the highest point.

Multiple Choice

Which of the following is the best example of chemical energy being transformed into light energy and heat energy?

• boiling water on an electric stove

• turning on a battery powered flashlight

• watching a movie on television

• using a solar panel to charge batteries

Multiple Choice

Look closely at the illustration. According to the law of conservation of energy, what happened to the energy of the ball in the illustration?

• Both the potential energy and the kinetic energy remained unchanged.

• Potential energy was transformed into kinetic energy.

• The amount of total energy in the ball increased.

• The amount of total energy in the ball decreased.

The correct answer is H (Substance Y would have less mass than substance Z

would have if they had the same volume).

Distractor Rationales

F.

The mass of substance X and the mass of substance Y cannot be determined from the graph if the volume of each substance is not known.

G.

The volume of substance W and the volume of substance X cannot be determined from the graph if the mass of each substance is not known.

I.

Substance Z has a greater mass per volume than substance W; therefore, the mass of substance Z would be greater than substance W if they each had equal volumes

Multiple Choice

• The lift is equal to the drag.

• The lift is less than the weight.

• The thrust is equal to the weight.

• The thrust is greater than the drag.

Multiple Choice
