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.
