Insert the information in the form and the calculator will determine the normal force.

What is the normal force?

Normal force is the component of a contact force that perpendicular to the surface that an object contacts.

How to calculate normal force?

To calculate normal force you should use the following formula:
Fn = m * g * cosΘ
where:
Fn = normal force
m = mass
g = acceleration due to gravity and it's equal to 9.80665
Θ = inclination agnle

Why use normal force?

The normal force is used to in order to keep a surface solid because without normal force an object would pass right through a surface.
