Across
- 1. the ability to move a large resistance by applying a small effort
- 3. a simple machine that is an inclined plane wrapped in the form of a cylinder
- 6. 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
- 7. a force that acts like a brake on moving objects
- 9. a rotating wheel-like object with teeth around its rim used to transmit force to other gears with matching teeth
- 10. 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
- 11. a simple machine that is a special kind of lever; effort applied to the outer edge of the wheel is transmitted through the axle

Down
- 1. a device that does some kind of work by changing or transmitting energy
- 2. a measure of turning effort
- 4. a system of levers used to transmit motion
- 5. a way of changing one kind of effort into another kind of effort
- 6. the effort applied to a given area
- 8. the speed of an object; also the rate of change in an object's motion
- 13. a simple machine that consists of a bar and fulcrum, used to increase force or decrease the effort needed to move a load
