    The normal force ("N" in the image) is indeed perpendicular ("normal") to the surface of contact. For the case of an object on an incline, its magnitude is

    N = m*g*cosΘ

    where Θ is measured from horizontal.

    When Θ = 0, cosΘ = 1 and the normal force is equal to the weight. As Θ approaches 90º, the normal force due to the weight approaches zero.

    If other forces are present, they can affect the normal force depending upon their direction.

    Hope this helps!
