Car sick............roller coasters.......?

Ok so i'm 13 and i've never been on a roller coaster or any type of ride besides a ferris wheel :P We're going to an awesome amusement park for band(we're performing and then riding rides) tomorrow and i want to know if i will get sick easily. I get car sick a lot when i ride in buses/cars and i need to know if that will affect me tomorrow. Also, whats a roller coaster like?? haha thanks :)
