Ch. 4: Work and Energy
Across
- 5. Law of __________________: States that energy cannot be created or destroyed, only converted from one form to another or transferred from one place to another
- 8. The ratio of output work to input work; often measured in percent
- 10. Energy due to motion
- 11. The sum of the kinetic energy and potential energy of the objects in a system
- 12. A device that changes the force or increases the motion from work
- 14. Potential energy that is due to the gravitational forces between objects
- 15. Anything around which you can imagine a boundary
- 16. The ability to cause change
Down
- 1. A combination of two or more simple machines
- 2. A machine that does work with only one movement of the machine.
- 3. Energy that is stored due to the interactions between objects
- 4. Force applied through a distance
- 6. The ratio of the output force to input force
- 7. The rate at which energy is converted
- 9. Potential energy that is due to chemical bonds
- 13. Potential energy that is stored by compressing or stretching an object
