Decide if each description below is an example of a change caused by energy. From the drop-down menu, choose "IS" if it is an example of a change in energy and "IS NOT" if it is not an example of a change in energy. A fireworks show an example of a change in energy. A child growing an example of a change in energy. A ball on the ground an example of a change in energy. A plant making food from the Sun an example of a change in energy. A car starting an example of a change in energy. A bat hitting a ball an example of a change in energy. An oven heating up an example of a change in energy.

The car's motion can be divided into three different stages: its motion before the driver realizes he's late, its motion after the driver hits the gas (but before he sees the police car), and its motion after the driver sees the police car. Which of the following simplifying assumptions is it reasonable to make in this problem?

a. During each of the three different stages of its motion, the car is moving with constant acceleration.

b. During each of the three different stages of its motion, the car is moving with constant velocity.

c. The highway is straight (i. e., there are no curves). d. The highway is level (i. e., there are no hills or valleys).
