The normal force is always perpendicular to the surface, and since there is no motion perpendicular to the surface, the normal force should equal the component of the skier’s weight perpendicular to the slope.
Normal Force: Remember that a normal force F N is always perpendicular to the surface that you are on. Since this surface is slanted at a bit of an angle, the normal force will also point at a bit of an angle.
11 Αυγ 2021 · Since only the normal force n and one component of the weight w acts along this direction, then we get: ∑F = 0 ⇔ n − w ⊥ = 0 ⇔ n = w ⊥. Now you just need to find the perpendicular component of the weight. That turns out to include the cosine of the angle due to trigonometry: w ⊥ = mgcos(α).

for the direction perpendicular to the plane. Of course, since there is no motion in this direction, \(a_y\) is zero. This gives us immediately the value of the normal force: \[ F^{n}=F^{g} \cos \theta=m g \cos \theta \label{eq:8.17} \] since \(F^g = mg\).
