  1. Kinetic and Potential Energy Miss Friend

  2. What is kinetic energy?

  3. What describes energy that is stored due to the height of an object from the ground?

  4. Which of the following has kinetic energy?

  5. A roller coaster at the top of a hill is an example of which type of energy?

  6. ME = KE + PE Chase pushes a toy car down a hill. After 5 seconds, the car has a kinetic energy of 100 J and a gravitational potential energy of 20 J. What is the car’s mechanical energy at that time?

  7. Gravitational Potential Energy = mass x 9.8 m/s² x height What is the gravitational potential energy of the book sitting on the shelf?

  8. Which object has the most kinetic energy? Three objects are rolling down a hill at the same speed. Object 1 has a mass of 1 kg; object 2 has a mass of 1.5 kg, and object 3 has a mass of 3 kg.

  9. Which of the following has elastic potential energy?

  10. Which of the following best illustrates chemical potential energy?

  11. True or false An object with a greater mass has greater kinetic energy.

  12. Think about it… If Tim were to jump out of a hot air balloon high in the sky, describe how gravitational potential energy changes as he falls. Then, describe how Tim’s kinetic energy changes when the parachute opens.

  13. Think about it… Describe the relationship between a moving object’s mass and its kinetic energy. Assume a balloon and a basketball are thrown at the same speed, which ball would have the most kinetic energy and why?

  14. PAIR SHARE Describe the relationship between a moving object’s mass and its kinetic energy. Assume a balloon and a basketball are thrown at the same speed, which ball would have the most kinetic energy and why? If Tim were to jump out of a hot air balloon high in the sky, describe how gravitational potential energy changes as he falls. Then, describe how Tim’s kinetic energy changes when the parachute opens.
