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? **
It will be least for the steepest slope
** As slopes increases will time intervals increase, decrease or show no pattern? **
decreasing

hen i placed the domino on the left side, the ball did not roll to touch the bracket.I am not sure if thats what was supposed to happen. But now the direction of ramp is changed,just by changing the position of domino to the left end

** Do your results support or fail to support your hypothesis about increasing or decreasing times? **
It supported the hypothesis.The time interval is decreasing with increasing the slope.the steeper the slope(with 3 domino),lesser the time interval.
** How do you think ave velocity is related to slope? **
The average velocity is inversely proportional to the slope.The steeper the slope,less time interval and more the average velocity.
** Speculate on why ave velocity changes with slope. **
Gravity acts more on steep slope.
** How could you test your speculations? **
