Quiz: Study Kinetic Energy with a Rube Goldberg Machine

Directions: Select the correct answer(s).
1. Which description best describes kinetic energy?
Correct.
Incorrect.
2. Ebony uses a marble to knock over the first of a series of dominos, resulting in the marble knocking over several of the dominos. Ebony wants it to knock over only the first domino. What can she do to solve the problem? Select all that apply.
Directions: Use the following explanation to select the correct answer(s) for questions 3 and 4.

Marquis is designing a Rube Goldberg machine. He wants to use a remote-control car that can roll at 25 cm/s and at double that speed (50 cm/s). His car weighs 50 g, but he can add weights to double its mass (100 g).

3. Which configuration should Marquis choose if he wants his car to have the most kinetic energy possible? Select all that apply.
4. Select which statement is correct.
Correct.
Incorrect.
5. In your own words, explain how knowing the concept of kinetic energy can help you plan and build or design and build a Rube Goldberg machine.
