## BIG IDEAS
- A component of the surface force, the force perpendicular to the surface.
- Prevents the object from passing through the surface.
- The normal force is a reaction force.
- The magnitude of the normal force can vary depending on other forces acting on the object.
### Symbol
$F_N \quad or \quad N$
### SI Unit
[[newton]]
### Formula
$F_N = mg \ cos(\theta)$
Where
$m$ is the mass of the object,
$g$ is the acceleration due to gravity, and
$\theta$ is the angle
