How does the inclination of a plane affect the speed of how fast objects will roll across it?

Question

If you have any websites that would be good sources of information, please list them! Anything at all will help, since this is a science fair project. Thanks!

Answer 1

Yes. Just imagine having planes at different inclinations. The object will remain stationary on the plane at 0 degrees, and as the inclination increases, the object will accelerate more and more until the plane is vertical and the object is freefalling.
