Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. What is kinetic energy?
Energy of position
Energy of motion
Stored energy
Chemical energy
2. Which two factors primarily affect the amount of kinetic energy an object has?
Height and mass
Mass and velocity
Temperature and color
Shape and density
3. The formula for kinetic energy is KE = 1/2 * m * v^2, where 'm' stands for and 'v' stands for .
4. An object at rest has kinetic energy.
5. A soccer ball with a mass of 0.45 kg is kicked with a velocity of 18 m/s. Calculate its kinetic energy.
6. Describe how kinetic energy is transformed into other forms of energy when a car brakes to a stop.
7. If you double the mass of an object, its kinetic energy also doubles (assuming constant velocity).
True
False
8. Kinetic energy can be created or destroyed.
True
False
Match the term with its definition.
9. Joule
a. The rate at which work is done
10. Work
b. Unit of energy
11. Power
c. Force applied over a distance
12. The diagram below illustrates the concept of an energy pyramid. While not directly about kinetic energy, it shows how energy is transferred in an ecosystem. In your own words, explain how the concept of energy transfer relates to kinetic energy.
