Homework Help! Involve roller coasters!

I need an idea on how to connect roller coasters to Vectors or Projectile Motion! It's for my physics power point presentation! I thought about the chiller launching off a track but if there are any other ideas.........!Thanks!  Enought with the exclamation points!

Try one of the coaster link sights and you will find links to a number of sights that have information on the physics of coasters.

Projectile motion? Perfect!

Given a particular velocity and angle an object will tend to follow a ballistic path, which you can predict. Once you predict that path, you can compare it to the track profile and see where the riders are going to go (ballistic path) versus where the train is going to go (track path). Voila: You've just predicted airtime and whether the ride might be safe.

Or you could go the projectile route...you've seen the videotape of someone floating an orange on Superman: The Escape, right? You could demonstrate the science behind that experiment, perhaps even showing how the action varies in different reference frames.

Well, it's a couple of thoughts, anyway...!

Or you could show how the normal force with banking etc. causes the train to follow the track (well, that and the upstops and guide wheels :P)

The legend lives!

You could make it like those new Volkswagon turbo commercials...ya know...the ones that show all this technical crap then this normal person just says "uhh...that means it goes faster?"  Instead  here you can show some ACEr sayin "uh, does that mean it has lots of air?"
