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 ball would take the least amount of time to roll down the steepest ramp.
** As slopes increases will time intervals increase, decrease or show no pattern? **
For the slopes fro least to greatest the time intervals wouls decrease respectively with the slopes.

This data was collected with the first 5 coming from the ramp being raised on the righ and then from the left. The data leads us to beieve that the time is not different from right to left or from left to right.

The path was collected the same as with using the one dominoe. The time to travel down the ramp decreased but there was still no signifficant difference between it being from the right or left.

The collection was the same as the previous with the time to travel down the ramp decreasing even more.
** Do your results support or fail to support your hypothesis about increasing or decreasing times? **
The results support the hypotheses that the time for the ball to travel down the ramp would decrease with each addition of a dominoe. The steeper the ramp the less time it takes to travel down the slope.
** How do you think ave velocity is related to slope? **
With the ramp steadily increasing the velocity of the ball traveling down the ramp increases. This is shown whe the ball went down the slop e with one dominoe the bracket at the bottom barely moved But when you use three the movement of the bracket is more sid=gnificant.
** Speculate on why ave velocity changes with slope. **
The weight of the steel ball reacting with the force of gravity against it.
** How could you test your speculations? **
try doing the experiment in a vacuum tube so that there would not be any affect from gravity.

Excellent report.
