Here's why:
* Inclined Plane: An inclined plane is a flat surface that slopes at an angle to the horizontal. It helps to move objects up or down with less effort than lifting them vertically.
* Wedge: A wedge is a triangular tool with a thick end and a thin end. When you apply force to the thick end, the thin end splits or separates the object.
How the wedge works:
1. Imagine splitting a piece of wood: You place the wedge's thick end against the wood and apply force to the thin end.
2. The thin end acts like an inclined plane: It pushes the wood fibers apart.
3. Two inclined planes: The wedge essentially has two inclined planes meeting at the tip. Each side of the wedge acts as an inclined plane that pushes the wood apart.
In essence, the wedge uses the principle of inclined planes to multiply force and create a splitting or separating action.
