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? **
I think the the steeper the ramp gets the quicker the ball will reach the end.
** As slopes increases will time intervals increase, decrease or show no pattern? **
I think the the time intervals will be decreasing.

The previous 10 numbers are the time it took the steel ball to roll down a 30cm incline with one domino placed under the steel channel. The measurements are in seconds.

** Do your results support or fail to support your hypothesis about increasing or decreasing times? **
Yes, my results support my hypothesis regarding the relationship between the time intervals and slopes.
** How do you think ave velocity is related to slope? **
I think that the average velocity is directly proportional to the slope of the ramp. As the slope of the ramp increased, the time interval decreased at a constant proportional rate.
** Speculate on why ave velocity changes with slope. **
The higher the slope is the quicker the objects acceleration will increase
** How could you test your speculations? **
time the ball at different points during its travel down the incline and see if the acceleration is in fact getting larger.
