How do ramps facilitate the movement of heavy objects?

Ramps are effective tools for moving heavy objects because they reduce the amount of force that is needed to lift an object to a higher elevation. When you use a ramp, the effort required to move an object up a slope is less than lifting it straight up. This is due to the mechanical advantage provided by the inclined plane shape of the ramp.

As an object is pushed or pulled up the ramp, the gravitational force acting on it is distributed over a longer distance, thus allowing a smaller force to achieve the same height compared to lifting it vertically. The steeper the ramp, the more force is needed, but a gentler slope allows for a greater mechanical advantage and reduces the required output force from the person or machine moving the object.

In this way, ramps make it easier to move heavy items by allowing workers to apply less force than would be necessary for lifting the load straight up, which is particularly advantageous when dealing with heavy or bulky objects.
