Formule

## Moment of Inertia Moment of inertia (I) is the rotational analogue of mass. It depends on mass distribution relative to the rotation axis. ### Formulas by Shape - **Solid Sphere:** I = (2/5) * m * r² - **Hollow Sphere:** I = (2/3) * m * r² - **Solid Cylinder/Disk:** I = (1/2) * m * r² - **Thin Rod (center):** I = (1/12) * m * L²

Exemple Résolu

A solid sphere of mass 5 kg and radius 0.2 m.

  1. 01For a solid sphere: I = (2/5) * m * r²
  2. 02I = 0.4 * 5 * 0.04
  3. 03I = 0.4 * 0.2
  4. 04I = 0.08 kg·m²
