Enter the vehicle’s mass and the car’s acceleration into the calculator to determine the wheel force.

Wheel Force Formula

The following equation is used to calculate the Wheel Force.

WF = VM * A / W
  • Where WF is the wheel force (N)
  • VM is the vehicle mass (kg)
  • A is the vehicle acceleration (m/s^2)
  • #W is the number of wheels

To calculate the wheel force, multiply the vehicle mass by the acceleration, then divide by the number of wheels.

What is a Wheel Force?


A wheel force is the total force generated by each wheel on a car due to its rotation and friction between the road.

How to Calculate Wheel Force?

Example Problem:

The following example outlines the steps and information needed to calculate the Wheel Force.

First, determine the vehicle mass. In this example, the vehicle mass is found to be 1000kg.

Next, determine the vehicle acceleration. For this problem, the vehicle acceleration is found to be 15 m/s^2.

Next, determine the number of wheels. In this case, the car has 4 wheels.

Finally, calculate the Wheel Force using the formula above:

WF = VM * A / #W

WF = 1000 * 15 / 4

WF = 3,750 N


What factors can affect the wheel force of a vehicle?

Several factors can affect the wheel force, including the vehicle’s mass, acceleration, the number of wheels, tire pressure, road conditions, and the type of terrain the vehicle is driving on. Changes in any of these factors can lead to variations in the calculated wheel force.

How does tire pressure influence wheel force?

Tire pressure can significantly influence wheel force. Properly inflated tires ensure optimal contact between the tire and the road, allowing for better force transmission. Over-inflated or under-inflated tires can reduce the efficiency of force transfer, affecting the vehicle’s acceleration and braking performance.

Why is it important to calculate wheel force in vehicle design?

Calculating wheel force is crucial in vehicle design for several reasons. It helps engineers optimize the vehicle’s performance in terms of acceleration, braking, and handling. Understanding wheel force is also essential for designing safer vehicles that can effectively transfer forces during different driving conditions, thereby improving the overall driving experience and safety.
