An inclined plane that moves is referred to as a wedge. The wedge is a simple machine that consists of two inclined planes joined together, which allows it to convert a force applied along its length into a force that is directed perpendicularly to its face.
Wedges are commonly used in various tools and applications, such as knives and axes, where they help to split or lift objects. When a force is applied to the wide end of the wedge, it drives the two inclined planes together, effectively separating or lifting whatever is in its path.
