1:58 how we got 1/2
Inverse square law is -2? How?

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

Appreciate it!

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

[@astronaughtpov]

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!

In the solution to the example, is the 'v' the velocity of the center of mass of the galaxy?

[@astronaughtpov]

I'm glad you brought this up. The velocity in the example refers to the mean velocity of the galaxy.
