- 7. a sloping surface that reduces the amt. of force required to lift an object
- 10. force times distance
- 12. measures how well a machine converts input energy, work and power into output energy, work and power
- 13. tool used to measure the weight of an object or the force on an object
- 14. unit used to measure mass of objects
- 15. a rigid bar or board that is free to move around a fixed point (fulcrum),
Down
- 1. is necessary to do work and the object must move in response to the force
- 3. tool used to measure the mass of an object
- 4. device that makes work easier for us by allowing us to push or pull over increased distances
- 6. unit used to measure weight or force
- 8. has a grooved wheel with a rope running along the groove, can change the amt. or direction of force applied
- 9. is the standard unit for measuring work
- 11. the ability to cause change or a property that enables something to do work
