That is not quite right. Momentum= mass x velocity. So a smaller mass moving at greater velocity can have the same momentum as a slower velocity larger mass object.

LeeRoy is right in the sense that at the same velocity (MPH) the train has greater momentum though. So what Seed is ultimately arguing is that his character so outclasses LeeRoy's in terms of the ability to produce velocity that he can overcome his extreme mass disadvantage. I'm not sure if the sheets actually substantiate this claim, but it is what he's saying.

Also I have no idea why I'm here, except that I felt your assertion that LeeRoy was about to be 'heavily corrected' was a bit pre-emptive. Also LeeRoy is still technically representing the Arena in an OOC sense, so I'm obviously in his corner.

I'll head off now.
