Your 'ball down ramp' report has been received. Scroll down through the document to see any comments I might have inserted, and my final comment at the end.
** Your general comment **
** Will a steeper ramp give greater or lesser time? **
the steeper the slope, the shorter the time interval
** As slopes increases will time intervals increase, decrease or show no pattern? **
I think the time intervals will decrease

the data shows the time it takes for the ball to roll from one end of the ramp to the other, and it was collected by the method given in the instructor's notes.

** Do your results support or fail to support your hypothesis about increasing or decreasing times? **
yes. the larger the slope, the faster the time
** How do you think ave velocity is related to slope? **
I think that gravity has a constant effect on the ball as it travels down the ramp, which in turn affects the velocity of the ball
** Speculate on why ave velocity changes with slope. **
I would wager that gravity and the weight of the ball combine to give a faster velocity
** How could you test your speculations? **
by putting the points on a graph of velocity vs. slope
