Which of the following statements are true about kinetic energy? Include all that apply.

. 13. A 1-kg object is accelerated from rest to a speed of 2.0 m/s. This object gains 4.0 Joules of kinetic energy.

F

3. If an object is on the ground, then it does not have any kinetic energy.

F

11. An object can never have a negative kinetic energy.

T

2. If an object is at rest, then it does not have any kinetic energy.

T

1. Kinetic energy is the form of mechanical energy which depends upon the position of an object.

F

10. Object A has a mass of 1 kg and a speed of 2 m/s. Object B has a mass of 2 kg and a speed of 1 m/s.Objects A and B have the same kinetic energy.

F

12. A falling object always gains kinetic energy as it falls.

F

14. If work is done on an object by a non-conservative force, then the object will either gain or lose kinetic energy.

F

4. The kinetic energy of an object is dependent upon the weight and the speed of an object.

F

5. Faster moving objects always have a greater kinetic energy.

F

6. More massive objects always have a greater kinetic energy.

F

9. An object has a kinetic energy of 40 J. If its speed were twice as much, then its kinetic energy would be 80 J.

F

. 7. Kinetic energy is a scalar quantity.

T

8. An object has a kinetic energy of 40 J. If its mass were twice as much, then its kinetic energy would be 80 J.
