Talk:Motion - Dynamics

F=ma is a simplification, that only holds true when mass is constant throughout the scenario. The true law statest that force is the derivitave of momentum with respect to time (dP/dt), where momentum (P) is equal to mass * velocity (P=mv). In situations where mass changes (for example, in rocket propulsion),   F=ma does not work.

Yep. You can add it to the article :) --Jorge 17:10, 3 February 2007 (UTC)

I think the calculus is best left out of the high school physics. This topic is normally done in grade 11 where the students have no notion of calculus. Harvey 17:34, 30 August 2008 (UTC)

Why are these pages categorized as "moved from Wikibooks"? All this has been created here. Harvey 23:30, 30 August 2008 (UTC)
 * Thanks for asking - the page was imported in the past from Wikibooks, please see, Erkan Yilmaz uses the Chat (try) 22:16, 1 September 2008 (UTC)

Well I guess the page with the title on it was imported, but I wrote all of the present content right here! Ditto for kinematics and Mechanics. Should I have written it in Wikibooks instead? Also, when you come in via the "main page" you have to go through School Subjects, Physics and Astronomy, Physics and then you see just an alphabetical list. I would expect a wikiversity subject to have some kind of course-like organization with a suggested order of topics to be studied. Harvey 04:58, 3 September 2008 (UTC)
 * Hello Harvey, you decide where you want to participate. Here you find a little help what both projects are for: FAQ and then see "What is the difference between Wikiversity, Wikibooks, and even Wikipedia?". That is only text, best is always to live for a little while in a wiki project and see how the atmosphere/culture is.
 * If you want you can remove the category:Pages moved from Wikibooks from the learning resource.
 * About structure: feel free to add a comment at Wikiversity talk:Main Page or Colloquium or a link to here, so more people see that. See you around, Erkan Yilmaz uses the Chat (try) 18:46, 4 September 2008 (UTC)
