Simple Machines

2. Machine - A machine made up of two or more simple machines working together.
3. - A force that resists motion when two surfaces rub together.
5. - When a force moves an object over a distance.
7. Advantage - How much a machine multiplies the effort force to make work easier.
8. Advantage - When a machine allows a task to be done faster or over a greater distance.
10. Force - The force you apply to a machine (the effort).
11. - A wheel with a rope or chain that changes the direction of a force and helps lift loads.
16. - A simple machine with sloping sides used to cut or split things (e.g., knife, axe).
17. - A measure of how much useful work a machine does compared to the energy put in.
18. - The object that a force is used to move or lift.

1. - The fixed point around which a lever pivots.
4. - A push, pull, or twist that makes an object move, stop, or change direction.
6. - An inclined plane wrapped around a cylinder that helps hold objects together or lift materials.
8. Machine - A device that makes work easier by changing the size or direction of a force.
9. of Force - The way a force acts — pushing, pulling, or twisting.
12. - A rigid bar that pivots around a fulcrum to move a load.
13. and Axle - A wheel attached to a rod that allows movement or rotation with less force.
14. - The force applied to make a load move.
15. Plane - A sloping surface that helps lift heavy objects with less effort (e.g., ramp).
19. Force - The force the machine applies to the load.
