Normal Force Calculator

Normal Force is the force that acts perpendicularly to the surface. It is the quantity of force used for counteracting the gravity.

Formula to calculate normal force at rest or level surface is given by:

Normal Force Calculator

Formula to calculate normal force on an incline surface is given by:

Normal Force Formula

N = Normal Force
m = Mass of the object
g = Acceleration of gravity [9.8m/s2]
x = Angle of Inclination

Enter the input values in our below online normal force calculator and click calculate button to find the answer.

Note: If you're trying to calculate normal force at rest then enter the angle of inclination as zero in the below calculator.

Mass of the Object [m]: [kg]
Acceleration of Gravity (g): [m/s2]
Angle of Inclination (x): [degrees]
[Enter 0 for calculating normal force on level surface]
Normal Force [N]: [N]
