Across
- 2. the ability to cause change; measured in Joules (J)
- 5. Law of _______________________ states that energy cannot be created or destroyed
- 7. ratio of the output force exerted by a machine to the input force applied to the machine
- 8. transfer of energy when a force is applied over a distance; measured in Joules (J)
- 9. energy a moving object has because of its motion; determined by the mass and speed of the object
- 11. machine that does work with only one movement; examples include lever, pulley, wheel and axle, inclined plane, screw, and wedge
- 13. energy that is stored by compressing or stretching an object
- 14. energy that is stored to the interactions between objects
- 15. energy that is due to chemical bonds
- 16. ratio of the output work done by the machine to the input work done on the machine, expressed as a percentage
Down
- 1. machine that is a combination of two or more simple machines
- 3. energy that is due to the gravitational force between objects; also GPE
- 4. rate at which energy is converted; measured in Watts (W)
- 6. region or set of regions around which a boundary can be defined
- 10. device that makes doing work easier by increasing the force applied to an object, changing the direction of an applied force, or increasing the distance over which a force can be applied
- 12. energy that is the sum of the potential energy and kinetic energy of the objects in a system
