*****Making A Small Roller Coaster - A couple of questions (please answer ASAP)*****

Hi

I am going to make a small roller coaster and I had a couple of questions about it.

1) What materials are the best in making different parts of a roller coaster model? (The tracks, Loops, Base and ...)

2) Does the first hill have to have more hight than the other hills?

3) How is designing the roller coaster possible if I don't know the friction of the track?

Fun Question) What theme do you prefer in a roller coaster?

IF YOU KNOW THE ANSWER FOR ANY OF THESE QUESTIONS, PLEASE REPLY. IT'S GREATLY APPRECIATED.

Thank You.

Hi, Incognito.
This might sound like a joke, but it isn't. Try to get your mitts on a copy of the 'Roller Coaster Tycoon' game. It's astounding how realistic it is. You can do any kind of experimental ride that you want to, and find the results very quickly.
As for one of your questions, in a normal situation the launching hill does have to be higher than any of the others. Realistically, though, you can have booster sections on the rails that can compensate if your gravitational potential isn't enough to get you over the next hump.
