Escalators and slanted conveyor belts are also forms of inclined plane.
Similarly, the flat surface of an inclined plane and wedge are examples of the kinematic pair called a sliding joint.
In 1586 Flemish engineer Simon Stevin derived the mechanical advantage of the inclined plane, and it was included with the other simple machines.
However the inclined plane was the last of the six classic simple machines to be recognised as a machine.
If the object is on a tilted surface such as an inclined plane, the normal force is less, because less of the force of gravity is perpendicular to the face of the plane.
If there is no friction between the object being moved and the plane, the device is called an ideal inclined plane.
