How does the presence of an incline affect the gravitational force acting on an object?

The presence of an incline affects the gravitational force acting on an object by distributing that force into two components: one acting perpendicular to the incline and the other acting parallel to the incline. This distribution occurs due to the angle of the incline.

Gravity always acts vertically downwards; however, when an object is placed on an inclined surface, we can resolve the gravitational force into these two components. The component of gravitational force that acts parallel to the incline is what causes the object to slide down if no other forces counteract it, while the perpendicular component is what press against the surface of the incline.

Understanding this distribution is essential because it explains how much of the gravitational force contributes to the motion of the object down the slope (the parallel component), and how much is held in check by the normal force (the perpendicular component). Therefore, the correct understanding reflects how the incline impacts the dynamics of the object rather than eliminating or increasing the total gravitational force.
