Hello, thanks for the question. Q is not linear momentum; it is the sum of the products of the particle's linear momentum and position vector. At 1:41, I say "linear velocity is mass times velocity." By this, I mean p_i = m_i x v_i. Since Q is dependent on linear momentum, the equation for Q will also contain these terms. I hope that helps!
I was like, am i tired or why am i not grabbing the concept then i realised playing vid fast and noting it down too lol. Though, a suggestion would be to slow a lottle down and add a little bit random extra examples for concept clarity!
1:58 how we got 1/2
Inverse square law is -2? How?
At 1:41, are we treating Q as linear momentum? A book I'm reading follows the same steps and I don't understand why Q is suddenly linear momentum

Wow, I'm fascinated by this incredible video. Thank you!!! :)
Appreciate it!

Omgggg how did I not find this before 🔥🔥🔥
Thanks for the kind words!
Thank you so much for this video! I through the structure of the video was super helpful :)
Yay, I'm so glad! I appreciate the comment.
In the solution to the example, is the 'v' the velocity of the center of mass of the galaxy?
I'm glad you brought this up. The velocity in the example refers to the mean velocity of the galaxy.
Extremely helpful, thank you!
That's good to hear! Thanks for the comment
감사합니다 선생님
Thank you so much!
Thanks!
