A while back I asked a question about maintaining speed with a minecart up a ledge. I did some maths (or math) and figured it out, answering my own question. However it did not seem effective in practice. I was wanting to find out more about minecart physics and understand it.
Does anyone have any knowledge of minecart physics they can share or quote from external sources.
I'd like to know about the changes in speed and kinetic energy/momentum when using different types of rail going uphill, downhill, flat, diagonal, and on a turn.
Once I have enough information to effectively calculate efficient minecart and rail solutions I shall place it on an edit at the end of the question for reference.
Thanks in advance!
