screw A simple machine made up of an inclined plane wrapped around a rod, used to hold objects together pulley A simple machine that has a rope or chain wrapped around the edge of a wheel; used to move an object up, down, or sideways

Whatever is produced by a cause; a result; what happened
A person, thing, or event that makes something happen; why something happens effect Whatever is produced by a cause; a result; what happened

force A push or a pull that causes something to move; a force changes the way an object moves friction The force caused by rubbing two objects together that causes that object to slow down or stop moving

gravity The force that pulls objects toward the center of the Earth; gravity is what gives us our weight magnetism The force that causes magnets to pull on objects that are made of certain metals, such as iron

pole The place on a magnet where the magnetic force is the strongest
work Something done whenever a force moves an object over a distance; the object moves in the direction of the push or pull

Simple Machine Inclined Plane
A tool that has few or no moving parts; there are 6 different kinds of simple machines Inclined Plane A simple machine that is a flat surface with one end higher than the other; a ramp

lever A simple machine made of a bar or board that is supported underneath by a fulcrum; a seesaw fulcrum The point on which a lever is supported and moves; an object is lifted more easily if you move the fulcrum closer to the object

Wheel and Axle A simple machine that has a center rod (axle) that is attached to a wheel Gear A Gear has a wheel with jagged edges like teeth that fit between the teeth of another gear, causing the wheel to turn.

Wedge A simple machine that is made up of 2 inclined planes that come together; used to cut or split an object
