Across
- 5. the effort applied to a given area
- 8. a simple machine that consists of a bar and fulcrum (pivot point), used to increase force or decrease the effort needed to move a load
- 10. a rotating wheel-like object with teeth around its rim used to transmit force to other gears with matching teeth
- 11. a simple machine in the form of a wheel with a groove around its rim to accept a rope, chain, or belt; used to lift heavy objects
- 14. a simple machine in the form of a sloping surface or ramp, used to move a load from one level to another
- 15. a force that acts like a brake on moving objects
- 16. a device that does some kind of work by changing or transmitting energy
- 17. the rate at which work is done or the rate at which energy is converted from one form to another or transferred from one place to another
Down
- 1. the thickness of a liquid, caused by the friction of its molecules rubbing together
- 2. a measure of turning effort
- 3. a measurement of the amount of effort needed to change one kind of energy into another
- 4. a simple machine that consists of two inclinedplanes placed back to back
- 6. a simple machine that is a special kind of lever, effort applied to the outer edge of the wheel is transmitted through the axle
- 7. a simple machine that is an inclined plane wrapped in the form of a cylinder
- 9. a way of changing one kind of effort into another kind of effort
- 12. the speed of an object also the rate of change in an object's motion
- 13. a system of levers used to transmit motion
