Simple Machines

2. A simple machine made of a wheel attached to a rod (axle) that helps move or lift loads with less effort.
7. A rigid bar that pivots around a fixed point (fulcrum) to lift or move loads.
8. A push or a pull that makes an object move, stop, or change direction.
10. An inclined plane wrapped around a cylinder that helps hold objects together or move materials.
11. A flat, slanted surface that helps move objects to a higher or lower place with less effort.
13. The force that resists motion when two surfaces rub against each other, affecting how simple machines work.
14. The force applied to a simple machine to make it work.

1. The benefit gained by using a machine to make work easier by reducing the effort needed.
3. A device that makes work easier by changing the force or direction of movement.
4. A wheel with a groove and a rope that can change the direction of a force and make lifting objects easier.
5. A measure of how well a machine converts effort into useful work without losing energy to friction or other forces.
6. The result of a force moving an object over a distance (Work = Force × Distance).
9. A device made of two inclined planes that move to split, cut, or push objects apart.
12. The object or weight that is being moved by a machine.
13. The fixed point on which a lever rotates or pivots.
