| Jan 2, 2021 at 0:35 | comment | added | R. Emery | Does I not equal r^2 m. Why does it surprise you that the same formula holds for an infinitesimal mass "dm"? | |
| Jan 2, 2021 at 0:27 | comment | added | R. Emery | dm is a small piece of the much larger mass M. r is the distance from somewhere to that particle of mass | |

| Jan 1, 2021 at 21:01 | comment | added | The Photon | @garyp, this form is probably presented to develop the moment of a distrbuted object from the formula for the moment of a collection of point masses. | |
| Jan 1, 2021 at 19:41 | comment | added | BioPhysicist | Don't trust anyone who writes the integral $\int r^2\,\text dm$ with limits from $0$ to $M$. | |

| Jan 1, 2021 at 19:23 | comment | added | garyp | That $\mathrm{d}m$ thing is not worth the few millimeters of space it saves on a page. Furthermore, it hides, as you have noticed, that the integral is over a spatial domain. And I share your shrugged shoulders over what it means mathematically. It does nothing but confuse people. IMHO it should be dumped in the trash bin. | |
