Wedge

A wedge is a simple machine that helps you cut, split, or push things apart using less effort.

It looks like two slanted sides joined at a thin, sharp edge, like a doorstop or a knife blade.

When you press or push on the thick end of a wedge, it sends the force down its slanted sides.

This force moves sideways, helping the wedge push apart the material around it.

A chisel, knife, ax, and even your front teeth are all examples of wedges that make cutting or splitting easier.

Imagine slicing an apple with a knife. The sharp edge goes in easily, then the wider part forces the two sides of the apple to separate.

The thinner and longer the wedge, the less force you need to use, which gives it more mechanical advantage.

That means a long, skinny wedge can split something with less effort than a short, thick one.

So next time you chop food or see someone splitting wood with an axe, think about how the wedge is helping you get the job done.
