Enter the rolling resistance coefficient and the normal force (N) into the calculator to determine the Rolling Friction Force. 

Rolling Friction Force Formula

The following formula is used to calculate the Rolling Friction Force. 

Froll = Crr * N

  • Where Froll is the Rolling Friction Force (N)
  • Crr is the rolling resistance coefficient 
  • N is the normal force (N) 

How to Calculate Rolling Friction Force?

The following two example problems outline how to calculate the Rolling Friction Force.

Example Problem #1:

  1. First, determine the rolling resistance coefficient. In this example, the rolling resistance coefficient is given as .86.
  2. Next, determine the normal force (N). For this problem, the normal force (N) is given as 100.
  3. Finally, calculate the Rolling Friction Force using the equation above: 

Froll = Crr * N

Inserting the values from above and solving the equation: 

Froll = .86 * 100 = 86 (N)

Example Problem #2: 

Using the same process as above, first define the variables required by the formula. In this case, these values are provided as the following:

rolling resistance coefficient = .75

normal force (N) = 200

Entering these values gives:

Froll = .75 * 200 = 150 (N)
