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 time required for the ball to reach the end of the slope will decrease with each increasing slope.
** As slopes increases will time intervals increase, decrease or show no pattern? **
The time intervals would be be will be increasing.

** Do your results support or fail to support your hypothesis about increasing or decreasing times? **
They support the hypothesis.
** How do you think ave velocity is related to slope? **
The average velocity increases as the slope of the ramp increases.
** Speculate on why ave velocity changes with slope. **
The slope of the ramp causes the acceleration to increase, which causes the velocity to increase.
** How could you test your speculations? **
You could verify this by determining the velocity and acceleration for each set of intervals.
