How to use this Friction Force Calculator 🤔

  1. There are input fields for Friction coefficient \((μ)\), Normal force \((N)\), and Friction Force \((F)\). Enter any of the two inputs, and third parameter is calculated..
  2. The calculator uses the formula, substitues given values, and calcuates the missing value(s).
  3. A missing value is calcuated and displayed in the input field. Also, the caculation is displayed under the input section.

What is Friction Force?

Friction force is the resistance that one surface or object encounters when moving over another. It acts in the opposite direction of the motion and depends on the nature of the surfaces in contact and the force pressing them together.

Calculating Friction Force

The friction force (F) can be calculated using the formula:

\( F = μ \cdot N \).

In this formula, the parameters are defined as follows:
