Simple Machines

3. – The point around which a lever moves.
5. force – The force exerted by a machine on the object being moved or lifted.
7. – A simple machine that converts rotational motion into linear motion, often used to fasten materials.
9. – A central shaft that the wheel rotates around in the wheel and axle system.
10. – A wheel with teeth that works with other gears to transmit motion or force in a machine.
11. advantage – The factor by which a machine multiplies the input force.
13. – A simple machine that uses a rope and a wheel to lift heavy objects.
15. – The transfer of energy when a force moves an object over a distance.
16. plane – A flat surface tilted at an angle to help lift objects with less effort.
17. – A twisting force applied in systems like levers or screws.

1. – The object that is being moved or lifted by a simple machine.
2. – The pivot point on a lever.
4. – Another term for an inclined plane, often used in a slope to reduce the effort of lifting.
6. advantage – The ratio of the output force to the input force in a machine.
8. and axle – A simple machine that consists of a larger wheel attached to a smaller axle, allowing movement with less force.
12. force – The force applied to a simple machine to do work.
14. – A rigid bar that pivots on a fixed point to lift or move loads.
15. – A simple machine with a sharp edge that is used to split or cut materials.
