    When you release a ball on a smooth plane at an angle to the horizontal of the floor it accelerates. Once leaving the plane, and travelling on the floor a defined measure is set to record the time taken to move from one place to the next. The quickest time is when the plane is at an angle of 37 degrees. Why is this? All I can think of is along the lines of GPE and KE. Does this phenomenon have a name for itself?

    is this not taking angular momentum into account? (i.e. treating the ball as a particle?)

    I'm not sure, it was something I did two years ago. I saw that the acceleration of the ball is equal to a = g sin theta. The experiment was an AS experiment and was intended to be a simple experiment.
