[edit] Contribution

This is my first contribution, so I hope I've done it right. I forgot to put in a message for the edit log, so here's what I did: The article was looking promising until it was wiped and later replaced with a copy of 'Elastic', so I reverted it to the 07:50, 2 May 2005 version and merged a couple of the more recent changes.

[edit] Equations

The equations were not displaying correctly, but I was able to fix the problem. All in all, you did a nice job.

[edit] Link contribution

According to policy, you shouldn't add external links to... A website that you own or maintain, even if the guidelines above imply that it should be linked to. This is because of neutrality and point-of-view concerns; neutrality is an important objective at Wikipedia, and a difficult one. If it is relevant and informative, mention it on the talk page and let other — neutral — Wikipedia editors decide whether to add the link.

I have never edited here before so I would rather have someone experienced decide if the following is appropriate content. I suggest someone add links to my pages on this topic with descriptions as follows:

"2-Dimensional Elastic Collisions Without Trigonometry" (http://www.geocities.com/vobarian/2dcollisions/) "Bouncescope - a simulator for 2-dimensional elastic collisions" (http://www.geocities.com/vobarian/bouncescope/)

[edit] Equation ?

How did you solve the equation, going from step 2 to step 3 ? You should explain how you removed v'2 in the v1=... equation and how you removed v'1 in the v2=... equation.

[edit] Re: Equations?

The equations for v1' and v2' are the result of basic but lengthy algebraic manipulations. The basic steps are: solving one equation for one unknown variable, substituting it into the other equation, resulting in an equation with one unknown, then proceeding to simplify, expand, collect like terms, move all quantities to one side of the equation, apply the quadratic formula, expand, collect like terms, take the square root, and simplify.

I didn't think it was necessary to include all these steps because the equations for v1' and v2' are already given in the Wikipedia entry without explanation, so I was actually just using those equations without having solved them myself.

[edit] Re: Re: Equations ?

Ok, thanks for clarifying! This article helped me a lot.

[edit] Merge with Elastic scattering

It might make sense to add more particle physics stuff to this page, but I don't think there needs to be two pages. Flying fish 02:15, 6 March 2007 (UTC)

I'd have to disagree, along with those who commented on the elastic scattering page. The two terms are used in very different contexts. A single page dealing with both would have to be careful to avoid confusion, and it simply isn't necessary. --Starwed 11:47, 3 April 2007 (UTC)

[edit] I disagree with such a merge.

I personally see a reason behind keeping Elastic Collision and Elastic Scattering as distinct pages. While there definitely are paraellels between the two processes, elastic scattering is inherently a quantum process whereas elastic collision is within the realm of Newtonian mechanics. Rephrasing this distinction, elastic scattering is a sub-microscopic, relativistic process whereas elastic collision is primarily a macroscopic, sub-relativistic process. Approaching the one model from the vantage of the other often leads to incorrect description of phenomena and so-called paradoxical behavior. Thus separating the models by having two different pages should be pedagogically accurate.
