Levers allow you to lift really heavy things just by spreading the force out over a greater area. You can think of opening a paint can with a screwdriver, playing on a seesaw, and even scissors as examples of levers. There are actually three different classes of levers which you will learn about below!

First Class Lever
The First Class Lever is the most simple type of lever. It is a First Class Lever because the fulcrum is between the effort and the load. A seesaw is the most common example of this lever. When the fulcrum is in the middle, then both sides need an equal force to push the other into the air.

Second Class Lever
The Second Class Lever is a little bit different than the First Class Lever. The difference is that the load is between the effort and the fulcrum. This lever can be found in simple bottle openers and even wheelbarrows!

Third Class Lever
The Third Class Lever is the most complicated one. The difference in this lever is that the effort is between the fulcrum and the load. This type of lever is used mostly for tongs and tweezers.
