Down
- 1. force exerted by a machine
- 2. ratio of the resistance force to the effort force.
- 3. the SI unit used for work.
- 7. Consists of two or more simple machines linked so that the resistance force of one machine becomes the effort force of the second machine.
- 9. the ability of an object to produce a change in itself or its surroundings.
- 11. states the work done on an object equals the change in kinetic energy.
- 12. force multiplied by the distance.
