Energy Unit Test Part 1: Correct answers to the questions in this section show mastery of the learning targets below.

- I understand what energy is.

- I understand the difference between kinetic and potential energy.

Which of the statements below is TRUE about energy (this means THREE of the statements below are FALSE, do not choose one of these FALSE statements).

Energy is the ability to cause change and do work.

Energy is something we can always see.

Energy is something that appears out of nowhere, and there is no such thing as a transfer of energy.

In the image above, which ball above best represents potential energy?

The ball the girl is holding.

Bird in flight.

A car parked on the top of a hill.

Skateboard laying on the sidewalk not moving.

Energy Unit Test Part 2: Correct answers to the questions in this section show mastery of the learning targets below.

- I understand how energy can be transferred from one object or system to another.

Which of the statements below is a TRUE statement and best describes the Law of Conservation of Energy?

Energy can never be created nor destroyed. It can only be stored or transferred. An example might be a student eating a sandwich (stored chemical energy), and that energy transfers to kinetic energy so the student can run around on the football field after lunch.

Energy can be destroyed and created. It is not stored or transferred. An example may be a car that is able to create its own power out of nothing (it does not need fuel of any kind!).

At which point does this diver have the MOST kinetic energy, and the LEAST potential energy?

True or False: The skateboarder above has transferred potential energy to kinetic energy, and back to potential energy again in this image from point 1 to point 4. Also, this skateboarder has the same amount of TOTAL energy no matter which position he is on the ramp. Hint: Remember Law of Conservation of Energy!

True

False
