CHAPTER 2 ENERGY
1. Visible light is an example of Electromagnetic energy 2. Change from one energy form to another is Energy transformation
3. Energy stored in the nucleus of an atom is Nuclear energy 4. Rate at which energy is transferred is Power
5. Energy is measured in units called Joules 6. An example of something that stores chemical energy is A match
7. The law of conservation of energy states that when one form of energy is transformed to another No energy is destroyed in the process 8. Potential energy that depends on height is Gravitational potential energy
9. When you rub your hands together friction transforms Mechanical energy to thermal energy 10. A spinning turbine has this type of energy Mechanical
11. Moving water can be used to produce electricity because Energy can be transformed into other forms 12. The ability to do work or cause change is Energy
13. You can calculate an object’s mechanical energy by Adding its potential and kinetic energies 14. Potential energy is Stored energy
15. When natural gas is used to heat water the energy transformation is Chemical energy to thermal energy 16. An example of kinetic energy is A rolling bowling ball
17. Energy associated with motion is Kinetic energy 18. Energy associated with motion and position is Mechanical energy
19. If an object has mechanical energy it can work on another object. 20. Electromagnetic energy travels in the form of waves. 21. If velocity of an object doubles its kinetic energy is multiplied by 4.
22. Work is the transfer of energy from one object to another. 23. A baseball flying through the air has kinetic energy.
24. Water running over a waterfall is potential energy converted to kinetic energy. 25. A truck has greater kinetic energy than a small car when going the same speed because the truck has greater mass.
