Understanding Normal Force

The normal force is the force that a surface exerts on an object to prevent it from penetrating the surface. It acts perpendicular (or "normal") to the surface.

How to Use This Calculator

  1. Enter the mass of the object in kilograms (kg)
  2. Input the angle of the inclined plane in degrees
  3. Click "Calculate" to get the normal force

Formula

For an object on an inclined plane, the normal force (N) is calculated using:

N = mg cos(θ)

Where:

  • m = mass of the object (kg)
  • g = acceleration due to gravity (9.81 m/s²)
  • θ = angle of inclination (degrees)
