Answer 1

Here are the answers to your questions:

4. The energy of motion is known as
**B) kinetic energy**

5. Kinetic energy depends on the mass and ___________ of an object.
**B) speed**

6. Which object has a greater amount of kinetic energy? A tennis ball that weighs 4 ounces, or a bowling ball that weighs 6 pounds.
**b) bowling ball**
(Note: Kinetic energy also depends on speed, so if the tennis ball is moving much faster than the bowling ball, additional context would be necessary to make a definitive comparison.)

7. An object has kinetic energy if it is at rest.
**B) False**

8. Which two factors affect gravitational potential energy?
**b) mass and height**
