I am doing my Science Fair project on Inclined Planes. My experiment mainly revolves around the ANGLE of the inclined plane determining the TIME it takes a ball to roll down the plane. I was wondering it I kept all of the other variables the same (length of the plane, weight of the ball) and only manipulated the angle of the plane, what the equation would be used to predict the time. I researched all that I could in books and online but everything I found gave me all of these complex equations that didn't have to do with angle (or at least I think they didn't). Any help would be appreciated, thanks!
