## 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:**

- First, determine the rolling resistance coefficient. In this example, the rolling resistance coefficient is given as .86.
- Next, determine the normal force (N). For this problem, the normal force (N) is given as 100.
- 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)
