1. Kinetic energy is the energy an object has due to its

• Position
• Mass
• Motion
• gravity

2. What is the standard unit of measurement for kinetic energy?

• Joule
• Volt
• Newton
• watt

3. What will happen to the kinetic energy if you double the mass?

• The kinetic energy would be cut in half
• The kinetic energy would double
• The kinetic energy would be the same
• The kinetic energy would turn to potential energy

4. If you throw a tennis ball and a baseball at the same speed, which would have more kinetic energy?

• Baseball
• Tennis ball

5. Kinetic energy can be calculated from what two measurements?

• Mass and temperature
• Weight and distance
• Speed and temperature
• Velocity and mass

6. How do mass and speed relate to kinetic energy?

• Increasing mass decreases kinetic energy
• As mass and speed go up, the kinetic energy of an object increases
• As mass and speed decrease, kinetic energy increases
• Speed and mass do not affect kinetic energy

7. Two asteroids in space are heading straight towards Earth. Asteroid A is traveling at 120 miles per hour. Asteroid B is traveling at 100 miles per hour. What additional information do you need to know to figure out how much kinetic energy each asteroid will have when they impact Earth?

• How far each asteroid is from Earth.
• If the impact spot is water or land
• The mass of each asteroid

8. At which point would the motorcycle have the greatest potential energy?

• A
• B

9. Which graph would most likely show a relationship between speed and kinetic energy?

• A
• B
