A wheelbarrow full of concrete mix that needs to be moved onto a platform could be moved either by lifting it above the ground and setting it onto the platform or by using an inclined plane. The advantage of using the inclined plane is that the work can be done -

The force over the inclined plane required to elevate the barrow is less than the straight surface as there was the tangential gravitational force acting on the barrow.

What is force?

The force is the push or pulls experienced by the object when interacting with the other object. The force applied is calculated with respect to the force experienced by the object.

On moving the wheelbarrow over a straight surface, the gravitational force acting over it requires more force to elevate it in the opposite spatial relation.

Over the inclined plane, the wheelbarrow experiences the tangent of the gravitational force over it, and less force is required to elevate the barrow to the same level as the straight surface.
