What is the primary function of an inclined plane?

The primary function of an inclined plane is to lift objects with greater ease. An inclined plane is a flat surface that is tilted at an angle to the horizontal. This design allows a force applied parallel to the surface to lift an object vertically with less effort compared to lifting it straight up. By spreading the effort over a longer distance, the inclined plane reduces the amount of input force required to elevate an object.

This principle is particularly beneficial when moving heavy loads or when the height that needs to be achieved is significant, making it easier to transport items to higher elevations without exerting a large amount of force in a vertical direction. The mechanical advantage gained by using an inclined plane makes tasks that would otherwise require considerable strength much more manageable.
