What happens when pushing objects on an inclined plane if the slope is smaller?

When pushing objects on an inclined plane, a smaller slope reduces the angle of the incline, which means that the gravitational force acting on the object has a less steep component working against the force you apply. This results in a reduced requirement for force to move the object upward, making the task more effort-saving.

In practical terms, the benefits of a less steeper incline allow for smoother movement of the object with less exertion. The force needed is a function of the sine of the angle of the incline; as the angle decreases, so does the sine value, thus requiring less input force to push or pull the object.

This principle illustrates how the mechanical advantage of an incline is achieved by spreading the effort over a longer distance and reducing the vertical component of the weight that must be overcome, thereby saving effort compared to a steeper incline.
