View group questions.

To print this group, add it to a test.

Scissors A wedge is a simple machine used to split or push apart objects. The sharp blades of scissors are an example of wedges. They help cut apart paper.

A wedge is two back-to-back inclined planes. The inclined planes give the wedge its triangular shape with a sharp edge. The sharp blade of an ax is a wedge. It helps split apart wood. Some wedges have more rounded ends. The ends of a fork are slightly rounded wedges that help break apart and pick up food.

A thin, sharp wedge is easier to use to push apart an object than a thick, dull wedge. A thinner wedge needs less force to push it through an object than a thicker wedge. But, it will need to be pushed over a longer distance.
