KEPE

1. Stored energy or energy due to position is known as Potential energy.

2. The formula for calculating potential energy is mgh.

3. The three factors that determine the amount of potential energy in an object are mass, gravitational acceleration, and height of an object.

4. Potential energy is measured in units of joules(J).

5. Mass must be measured in units of kg.

6. Gravitational pull must be measured in units of m/s2.

7. Height must be measured in units of m.

8. Calculate the potential energy of a rock with a mass of 55 kg while sitting on a cliff that is 27 m high.

9. What distance is a book from the floor if the book contains 196 Joules of potential energy and has a mass of 5 kg?

10. An automobile is sitting on a hill which is 20 m higher than ground level. Find the mass of the automobile if it contains 362,600 J of potential energy.

11. Energy of motion is known as Kinetic energy.

12. The formula for calculating kinetic energy is

13. The two factors that determine the amount of kinetic energy in an object are mass and velocity.

14. Kinetic energy is measured in units of joules(J).

15. Mass must be measured in units of kg.

16. Velocity must be measured in units of m/s. Energy, Work and Power
