Simple Machines

A wedge is an object that is wide at one end and pointed at the other, used to cut or split objects.

An inclined plane is a flat surface that is raised higher at one end, used to move objects up or down.

A wheel & axle is a simple machine consisting of a rod attached to the center of a wheel, making it easier to turn or move objects.

A compound machine is made up of two or more simple machines working together.

A pulley is a simple machine that uses a wheel and a rope to lift or lower objects.

A lever is a simple machine that consists of a bar that pivots on a fixed point called a fulcrum.

A screw is a simple machine that is an inclined plane wrapped around a pole, used to hold things together or lift objects.

Simple machines make work easier by allowing us to apply force in a more effective way.

The six types of simple machines are lever, pulley, inclined plane, wedge, screw, and wheel & axle.

A lever works by using a fulcrum to lift or move a load with less effort.
