Is it just me or is it surreal, inappropriate and impractical to explore every conceivable instance of physical collision (flyswatters, carpet beating)?
Surely we should stick to broad categories of collision and link out appropriately? -- Air 11:31, 28 Oct 2004 (UTC)
Collisions can be elastic, meaning they conserve energy and momentum, inelastic, meaning they conserve momentum, or totally inelastic (or plastic), meaning they conserve momentum and the two objects stick together.
I'm not sure about the phrasing of this: "inelastic, meaning they conserve momentum" implies that elastic collisions are also inelastic. Should it be "inelastic, meaning they conserve momentum but not energy"?

I think collision, in this article, is imperceptibly defined in the language of general physics. Isn't the part of definition collision means the action of a system appears vague? It would be better to use the term 'isolated' than to use the phrase external forces can be neglected. I found a better definition for collision from the book Fundamentals of Physics, 6th Edition,
"A collision is an isolated event in which two or more bodies (colliding bodies) exert relatively strong forces on each other for a relatively short time."
This definition seems more tangible and appropriate for the physics article. -- Ajinx999 ( talk) 09:50, 12 June 2008 (UTC)
This should be separated into a disambiguation and the "main" collision page... -- Ihope127 00:18, 18 August 2005 (UTC)
What is the equation for elastic collision and the equation for inelastic collision? —The preceding unsigned comment was added by 168.8.249.93 ( talk) 15:34, 26 April 2007 (UTC).
What fundamental interactions are at work in a collision? That is, what "force" in nature is actually responsible for the fact that two particles cannot occupy the same space? That would be a good discussion in this article I think. Mbarbier ( talk) 17:48, 25 July 2008 (UTC)
The connection between collisions (the physical concept) and "attacks" is extremely tenuous. Maybe link to other generic concepts pertaining to collision, e.g. Impact.
I suggest removing the sections "Mathematical description" (seems specific to some formalism in atomic physics, not general enough), "Cue Sports" (pointless!), and "Space Exploration". It's like discussing Sumo wrestling in an article about the physical concept of "Mass".—Preceding unsigned comment added by 188.141.24.227 ( talk • contribs)
I agree with the above user -- the section on collisions of molecules is completely opaque. It's not even clear what the problem statement is or what it's trying to solve. Mathematically it just says that you can put collision equations in matrix form. That section should either be removed or it should please be clarified.

I removed what appeared to be unnecessary indents. As I write this I cannot think of a reason to post on the talk page about such a minor edit but I'm feeling verbose, I suppose.
If anyone really loved those indents you need but speak reason for their return Mattman00000 ( talk) 07:05, 24 September 2016 (UTC)
