Itâs no wonder why rear-end collisions are also referred to as âwhiplash accidents.â. When it comes to car accidents, the state of Tennessee is strict.
The unit of Inertia is kg and the Moment of Inertia is kg*m^2.
For a point-like mass, the moment of inertia about some axis is given by mr2, where r is the distance to the axis, and m is the mass. For an extended body, the moment of inertia is just the sum of all the small pieces of mass multiplied by the square of their distances from the axis in question.
