Today we will be learning about simple machines.

What is a simple machine?

A simple machine is a device that allows you to do work easier.

Multiple Choice

What is work?

• The amount of force required to move an object.

• A device that allows you to move an object easier.

There are SIX simple machine types:

• Lever

• Wheel and Axel

• Inclined Plane

• Wedge

• Pulley

• Screw

This is a wedge.

A wedge has at least one sharp edge which either cuts or holds and object together.

This is a wheel and axel.

A wheel with a rod through its' center.

This is a lever.

It is a bar or rod that rests on one point called a fulcrum. These are used to lift things.

This is a screw.

A screw is a wedge with an incline plane wrapped around it.

This is a pulley.

A pulley usually has a rope and a grooved wheel and is used to lift and lower down loads.

The final simple machine is an inclined plane.

This is a ramp used to carry loads from one level to another level.
