Great, I'll try that. :-)

Thanks again. We were talking about a train moving at constant velocity - my friend has apparently forgotten that. I'll remind him. I also think it is nonsense, and I told him so, but neither of us knows enough physics to do the calculation, could you be kind enough to give me an example? Our...

Ok, thanks for the replies. I thought I had enough info there, so I emailed my adversary with the following: Yes, if we were getting off the train I agree with the first sentence, but we are talking about the effect (forces) the passenger would feel on the ride. The ground is irrelevant, so...
