Work and Energy

5. the transfer of thermal energy by the circulation or movement of a liquid or gas
8. the transfer of energy as electromagnetic waves
10. the energy that an object has because of the position, shape, or condition of the object
12. the unit used to express power; equivalent to a joule per second (symbol, W)
14. a measure of how hot (or cold) something is; specifically, a measure of the average kinetic energy of the particles in an object
17. a change of energy from one form of energy to another

1. the temperature at which molecular energy is at a minimum. ____ zero (0 K on the Kelvin scale or 273.16ºC on the Celsius scale)
2. the amount of work an object can do because of the object’s kinetic and potential energies
3. a force that opposes motion between two surfaces that are in contact
4. the transfer of energy as heat through a material
6. the transfer of energy to an object by using a force that causes the object to move in the direction of the force
7. the energy of an object that is due to the object’s motion
9. the energy transferred between objects that are at different temperatures
11. the rate at which work is done or energy is transformed
12. the transfer of energy to an object by using a force that causes the object to move in the direction of the force
13. the law that states that energy cannot be created or destroyed but can be changed from one form to another. ______ of energy
15. the capacity to do work
16. the unit used to express energy; equivalent to the amount of work done by a force of 1 N acting through a distance of 1 m in the direction of the force (symbol, J)
