What makes an object easy or difficult to rotate? Rotational inertia is a quantity that describes an object’s tendency to maintain its rotational motion about an axis. (1:02) Torque is equal to moment of inertia multiplied by the angular acceleration (1:44). Try opening a door by pushing it very close to the hinges. Feels silly right? (5:40) The episode ends by putting the brakes on a bicycle wheel (6:53).
The Question of the Day asks: (8:11)
If the radius and mass of a ball are both doubled, how does the moment of inertia change?
