Perpendicular axes theorem for NEET Physics

A quick, NEET-focused explanation of this topic from the Rotational Motion chapter of Physics.

What Is Perpendicular axes theorem?

The perpendicular axes theorem states that for a planar body, the moment of inertia about an axis perpendicular to the plane is the sum of the moments of inertia about two perpendicular axes in the plane.

Key Points to Remember in Perpendicular axes theorem

This is expressed as I = I_x + I_y.
