How does a wedge make work easier?

What is a wedge?


Which is a wedge ....    A nail or a bolt?






The nail goes into the wood because it has a point (it is the wedge).  The bolt will not go in no matter how much force we use because it has no point.

When you hit the nail, your push the point or wedge of the nail into the wood.  You use a force on the head of the nail which then pushes the wedge into the wood, cutting it and making a hole in the wood.
