Normal force on an inclined plane

Gives the component of the normal force exerted by a surface on a block resting on a plane tilted at angle theta, equal to the weight component perpendicular to the surface. It applies when the object stays in contact with the surface and has no perpendicular acceleration.

N = mg\cos\theta

What the symbols mean

normal force magnitude (\mathrm{N})
mass of the object (\mathrm{kg})
gravitational acceleration (\mathrm{m/s^2})
angle of incline relative to the horizontal
