* Gravity always acts downwards. This force is always directed towards the center of the Earth.
* On an incline, the force of gravity can be broken down into two components:
* Normal Force: This component acts perpendicular to the surface of the incline, preventing the object from falling through it.
* Parallel Force: This component acts parallel to the surface of the incline, causing the object to slide down.
In summary: While the force of gravity itself doesn't change direction, its effect on an object on an incline plane does. The direction of the force that actually causes motion is the parallel component of gravity, which is directed down the incline.
