Enter the inertial mass, change in velocity, and the change in time into the calculator to determine the inertia force.

Inertia Force Formula

The following equation is used to calculate the Inertia Force.

IF = IM * V/T

  • Where Where If is the inertia force (N)
  • IM is the inertial mass (kg)
  • V is the change in velocity (m/s)
  • T is the change in time (s)

What is an Inertia Force?

Definition:

An inertia force is a force acting on an object that causes its velocity to change. Inertia is a measure of the resistance of an object to change velocity. The greater the mass of an object, the greater the inertia.

How to Calculate Inertia Force?

Example Problem:

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

First, determine the inertial mass. In this example, the inertial mass is found to be 15kg.

Next, determine the change in velocity. For this problem, the change in velocity is found to be 3m/s.

Next, determine the change in time. In this case, the change in time is measured to be 2 seconds.

Finally, calculate the Inertia Force using the formula above:

IF = IM * V/T

IF = 15 * 3/2

IF = 22.5 N
