If you had first-year physics in college, you probably solved lots of problems with a ball rolling down a flat inclined plane. Did you ever wonder how to solve for the motion with a curved surface instead? Of course the same principles apply, but the forces are changing as the slope changes. So the math gets a bit more interesting!

You can change the track shape by clicking a button below. You can drag the ball with your mouse to change the starting position. Try modifying gravity or damping.
