Overview
A wedge is a simple machine consisting of two back-to-back inclined planes. It is used to separate objects, lift them, or hold them in place by converting a force applied to its blunt end into forces perpendicular to its slanted surfaces.

Pro Tips
Mechanical Advantage (MA) = Length / Width.
A longer, thinner wedge has a higher mechanical advantage.
In reality, friction significantly reduces the effective output force of a wedge.

Fun Facts
"Knives, axes, and chisels are all common examples of wedges."
"The wedge is one of the six classical simple machines defined by Renaissance scientists."
"Doorstops are wedges that use friction to stay in place."
