I've been looking through all the gravity/physics games in my responses, but they aren't enough. Can anyone tell me how to make a basic uncontrolled physics program? Again, I want the ball to be blue and the track to be black. Thanks.

Maybe check out the wiki pages:
Physics Engines
Creating a Simple Platformer
Simulating Gravity
Velocity

I'm not getting it. Can someone please give me a self-made script for physics(no user control at all) please? Before I ditch the idea?

Physics is not a very specific noun. What do you want the ball and track to be physically doing?

3 things.

1: Wha?
2: I want the ball to move on the track and fly off it for jumps if the user wants. Also I need it to be a scrolling project so that there's more room for the user.
3: Pie.
