Torque from inertia and angular acceleration

Calculates axial mass moment of inertia of a uniform solid disc.

Calculates axial mass moment of inertia of a thin ring.

Calculates mass moment of inertia of a uniform rod about its center.

Calculates rotational kinetic energy of a rigid body.

Calculates simplified undamped natural frequency of a mass-spring system.

Converts angular acceleration units; it does not derive acceleration from rotational motion.
