Use an angular data logging device to measure the rotational motion of a different objects. Introduces the concept of rotational velocity and rotational inertia and how they relate to torque.


  • measure angular velocity
  • calculate torque
  • calculate moment of inertia
  • use data logging equipment to measure rotational motion.
