What is a ramp used to raise an object called?

A ramp used to raise an object is called an inclined plane. An inclined plane is a flat surface that is tilted at an angle to the horizontal. This design allows for lifting heavy objects with less effort by spreading the distance over which the object is moved upward. Instead of lifting an object vertically, the inclined plane enables the object to be moved at an angle, reducing the amount of force needed to raise it.

Other options, like a lever, refer to a different type of simple machine that consists of a rigid beam that pivots around a point (the fulcrum), while the pivot and fulcrum are specific components involved in the operation of levers. However, an inclined plane specifically refers to the ramp structure designed for raising objects. Hence, the correct identification of a ramp as an inclined plane highlights its function as a tool for easier elevation of loads.
