- 2. - when a force of one newton is exerted over a distance of one meter
- 6. energy - energy of motion
- 8. - a kind of lever that can be used to change the direction of the force.
- 11. - the rate at which work is done
- 12. - small input force exerted through a large distance will produce a large output force over a proportional short distance
- 13. - a device that multiplies forces or changes the direction of the force
- 14. of conservation of energy - energy can not be created or destroyed
Down
- 1. - the work done against another force

- 5. theorem - Whenever work is done, energy changes
- 7. - a machine
- 8. energy - energy that is stored ready to be used
- 9. - work being done on one end, the other end does work on the load
