Rolling Ball on Incline
Effects of resistance are made small by rolling
Argue ball rolls down due to same cause as falling bodies. Reasonable? Obvious?
Argue equations will be the same as for falling bodies (but reduced acceleration). Reasonable? Obvious?
For constant acceleration, the total distance traveled from the start x increases as the square of the time t, x = 1/2 a t2 . For equal intervals of time t, x increases in the ratios: 1 : 4 : 9 : 16 : 25 : …..
