Rotational Motion
Angular acceleration, moment of inertia, angular momentum and pendulum calculators
Angular Acceleration Calculator
Calculate angular acceleration from angular speeds and time, torque and inertia, tangential acceleration, rotational kinematics or stopping time.
Moment of Inertia Calculator
Calculate mass moment of inertia for rods, disks, rings, cylinders, spheres, plates, boxes and point masses, with the parallel-axis theorem.
Pendulum Calculator
Calculate period, frequency, length, gravity or spring parameters for simple, physical and spring pendulum models.
Angular Momentum Calculator
Calculate angular momentum from moment of inertia and angular velocity, point-mass motion, RPM, frequency or torque impulse.
