Inertia Calculator – Instant Online Inertia Tool

This tool calculates the moment of inertia for different shapes based on user-provided dimensions.





How to Use the Inertia Calculator

To use this inertia calculator, follow these steps:

  1. Input the mass (in kilograms) of the object in the “Mass” field.
  2. Input the radius (in meters) in the “Radius” field.
  3. Input the velocity (in meters per second) in the “Velocity” field.
  4. Click the “Calculate” button to compute the inertia.
  5. The result will be displayed in the “Result” field.

How It Calculates

This calculator computes the inertia (also known as the moment of inertia) of a rotating object using the following formula:

Inertia (I) = Mass (m) * Radius squared (r2) + 0.5 * Mass (m) * Velocity squared (v2)

Where:
– Mass (m) is the mass of the object in kilograms.
– Radius (r) is the distance from the axis of rotation in meters.
– Velocity (v) is the speed of the object in meters per second.

Limitations

This calculator is designed to provide an approximate calculation of inertia for educational purposes. It assumes a point mass and does not account for the distribution of mass or external forces. For more precise calculations, especially for non-uniform objects, it is recommended to consult a physics professional or use advanced simulation software.
