What is a wedge!?
If we didn't have any simple machines our lives would be harder. Then we would have to work harder every day. A wedge is a simple machine. A wedge is two inclined planes together. It makes work easier because it splits objects apart. It can hold things together. Or it lifts the object. A wedge lift a object by going under the object to lift it.
An axe is a type of wedge and it is a simple machine. It cuts wood apart.
A knife is a wedge like the axe. It cuts food in half.
A nail is also a wedge. A nail holds things together.
