Rotational inertia

The resistance with which a rigid body opposes a change to its rotation is indicated by the mass moment of inertia. Here, the behaviour of the body depends on its mass and the distribution of this mass relative to the axis of rotation. Mathematically, the quotient of the rotary moment and the angular acceleration is the mass moment of inertia. Learn about Rotational inertia equipment for optimal educational outcomes..
