Rolling Resistance Calculator

Calculate Rolling Resistance Force

A dimensionless value. Typical ranges: 0.001-0.005 for train steel wheels on rail, 0.01-0.015 for car tires on hard road, 0.06-0.1 for bicycle tires.
The total mass of the object or vehicle for which you're calculating rolling resistance.
Standard gravitational acceleration on Earth is 9.81 m/s².
Discover the force that opposes motion when an object rolls on a surface with our intuitive Rolling Resistance Calculator. Quickly determine the rolling resistance force (Fr) using the coefficient of rolling resistance (Crr), mass (m), and gravitational acceleration (g). Perfect for engineers, automotive enthusiasts, and students studying vehicle dynamics or energy efficiency.

Formula:

The Rolling Resistance Force (Fr) is calculated using the following simple yet fundamental formula:

Fr = Crr × m × g

Where:

  • Fr = Rolling Resistance Force (measured in Newtons)
  • Crr = Coefficient of Rolling Resistance (a dimensionless factor)
  • m = Mass of the object or vehicle (measured in kilograms)
  • g = Gravitational Acceleration (standard Earth value is 9.81 meters/second²)
