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 steep ramp should be the least time due to increased acceleration.
** As slopes increases will time intervals increase, decrease or show no pattern? **
decreasing

I was thinking about how unlevel this table I'm working on is, that or the fact that living on the 3rd floor of a building built in the 60's may not have been the best choice.

Both directions showed a decrease in interval, with the right-2-left having an average decrease of .507 and the left-2-right having one of .950

** Do your results support or fail to support your hypothesis about increasing or decreasing times? **
yes. The higher the slope, the faster the ball traversed the distance.
** How do you think ave velocity is related to slope? **
The velocity of the ball will increase with the slope of the ramp. The ball expends its stored energy quicker on a steeper ramp.
** Speculate on why ave velocity changes with slope. **
The ball expends its stored energy quicker on a steeper ramp.
** How could you test your speculations? **
try a different ball or a different ramp.
