| Mar 26, 2019 at 21:18 | comment | added | Cleonis | @AaronStevens After searching around on meta.stackexchange.com: does this work? This is a link to a chat room I newly created chat.stackexchange.com/rooms/91568/gyroscopic-precession | |
| Mar 26, 2019 at 20:48 | comment | added | Cleonis | @AaronStevens I took the unusual step of posting a second answer, to discuss why the angular-momentum-vector-moves-in-the-direction-of-the-torque is problematic. I don't know whether the chat supports adding images, and I needed the diagram. I realize my plea to move to chat sounds hollow now. Ah well; I will look up how to create a chat. (Haven't created a chat before, only visited.) | |

Based on how torque and angular momentum are defined the relations arise. Yeah you're not understanding how each particle moves in the body, but that's why we define these terms. I wouldn't say it makes it a poor explanation, it makes it a concise one if you hold the definitions and Newton's laws to be true. | |
| Mar 25, 2019 at 23:31 | comment | added | Cleonis | @AaronStevens Stackexchange strongly discourages drawn out discussions in comment sections. I very much want to have this discussion, but I totally agree with stackexchange that comment section is not the place. Stackexchange chat has been created specifically for this kind of situation. It's past twelve in my time zone now, can we continue in stackexhange chat at a later time? | |
| Mar 25, 2019 at 23:25 | comment | added | Cleonis | @AaronStevens I'm aware of course that there are many parallels between linear mechanis and angular mechanics. Many of the expressions have a similar form, there are tables with expressions of the two displayed side by side. However the analogy is not exhaustive, and in the case of gyroscopic precession the difference is crucial. The linear momentum vector is a very direct concept. The angular momentum vector is a highly abstract concept. (This is pretty much all I can fit in a comment.) | |
| Mar 25, 2019 at 23:02 | comment | added | BioPhysicist | So if someone asked why satellites orbit the Earth and don't just fly off into space you would say telling them a centripetal force due to gravity causes the satellite's momentum to be constantly changing and thus form an orbit would not be a good explanation? | |
