• jar P to jar Q

• jar P to jar R

• jar Q to jar R

• jar R to jar P

In the graph, the dotted line represents the potential energy of the car and the solid line represents its kinetic energy.

A car is traveling down the highway and is pulled over by police officer, predict what changes MUST be made to the graph to reflect this situation.

• The dotted line would need to be vertical for a certain amount of time.

• The solid line would need to become horizontal on the x-axis for a certain amount of time.

• The solid line would need to reach zero on the y-axis at some point.

• The dotted line would need to reach zero on the y-axis at some point.

A student pushes a hollow ball and a solid ball at the same time with the same amount of force. The hollow ball and the solid ball have identical external measurements. Which statement demonstrates an understanding of Newton’s second law of motion?

• The solid ball will move a shorter distance due to its larger mass.

• The hollow ball will move a greater distance due to its less volume.

• Both the hollow ball and the solid ball will travel the same distance because they were both acted upon by the same outside force.

• The solid ball will move a greater distance because it will require more force to stop.

Energy cannot be created or destroyed. It can only be transferred from one form to another. Energy that is "wasted," does not disappear. Instead, it is transferred to its surroundings and spreads out so much that it becomes difficult to do anything useful with it. Incandescent light bulbs are very inefficient in energy transfer. Energy-saving lightbulbs, such as fluorescent bulbs transfer a greater proportion of electrical energy as light energy. In fluorescent bulbs what kind of energy is "wasted" in the energy transfer from electricity to light?

• heat energy

• kinetic energy

• chemical energy

• electrical energy
