Newton`s 2nd Law
... Normal force: Gravity pulls the object down the slope and into the slope. If we only consider the motion into the slope (perpendicular), the object has no perpendicular velocity. So the F= 0. Then the surface must push upward, equal and opposite to the perpendicular gravity component. Named the n ...
