Talk:Angular momentum

Motion other than linear motion through a fixed point of reference

Linear motion is when everything moves together in the same direction and through an in line spacial point of reference. And in this case, the momentum of motion of the moving system is proportional to the mass value times the velocity of motion. And all the parts of the moving system have the same direction and moment of motion. However, if there is motion of a system where the motion of the parts is not uniform, then there has to be a system for describing that otherwise type of motion. And in the case of the rotary motion of a system around its center of inertia, the motion is described as being at a certain angular velocity around the center, and the angular momentum is calculated as being the product of the mass times the angular velocity times the square of the distance from the center of inertia to the rms distance values of the parts of the system. This calculation has the effect of calculating the sum of the all the different angular momentum values of all the parts of the system.

Important word (needs to be, early in the lede)

The first line/sentence/period, does not mention the word "physics". 2001:2020:347:B643:151D:7814:4ACB:507B (talk) 17:33, 17 March 2024 (UTC)

 Done, as of simple.wikipedia.org/w/index.php?title=Angular_momentum&oldid=9420292 .--However, perhaps the end of the lede should mention that the idea (about those momentums), are part of "Ideal laws whatever".--Unlike giving 3 apples to each of 4 friends; in real life, then 12 apples were given.--If this was helpful, then fine. 2001:2020:347:B643:F96E:5E31:B65F:7346 (talk) 17:43, 17 March 2024 (UTC) /2001:2020:347:B643:151D:7814:4ACB:507B
