About This Product
In rotational dynamics, the torque needed to give a flywheel a set angular acceleration depends on its moment of inertia. A variable inertia bar lets students change the inertia of the rotating system and see that more torque is needed to speed it up when the inertia is larger. It supports lessons on rotational motion and the analogy between torque, moment of inertia and angular acceleration, and force, mass and linear acceleration.
