Which quantity is a scalar quantity? acceleration area displacement force velocity.
I = mr 2. It's a scalar quantity (like its translational cousin, mass), but has unusual looking units. [kg m 2 ]. Say it, kilogram meter squared and don't say it some other way by accident. For a collection of objects, just add the moments. It works like mass in this respect as long as you're adding moments that are measured about the same axis. I = â I = â mr 2. For an extended body, replace the summation with an integral and the mass with an infinitesimal mass. You add up (integrate) all the moments of inertia contributed by the teeny, tiny masses (dm) located at whatever distance (r) from the axis they happen to lie.
