Does the basic motion physics simulation account for Weights and materials?

Pretty self explanatory question but here's some context:

We are using 2012 Pro, and that doesn't come with the software that i'm seeing on all of the simulations on youtube. but we're trying to figure out how certain components effect eachother when we spin them around at 100 RPM, and that requires a realistic weight simulation.

TL;DR:

Does the basic motion physics simulation account for Weights and materials?
