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 **
the bracket was not right for the Pearl Pendulum experiment any suggestions. It had the glued on washer missing.

** Will a steeper ramp give greater or lesser time? **
the time required will go down as the ramp is steepest.
** As slopes increases will time intervals increase, decrease or show no pattern? **
the time would be decreasing
** Your report of 5 trials each way for 1 domino **
1st
1.523, 1,789, 1.758, 1.695, and 1.617
2nd
2.539, 2,726, 2.734, 2.75, 2.77
I figured the times would be about the same but the difference in the sides makes a difference when you are moving the domino.
** Your report of 5 trials each way for 2 dominoes **
1st
1.164, 1.055, 1.047, 1.102, 1.086
2nd
1.664, 1.367, 1.453, 1.500, 1.570
The data say the right end is faster than the left I think this because of the way I was pulling the domino out.
** Your report of 5 trials each way for 3 dominoes **
1st
0.961, 0.914, 0.992, 0.961, 0.938
2nd
0.984, 1.17, 0.984, 1.14, and 1.375
same as before.
** Do your results support or fail to support your hypothesis about increasing or decreasing times? **
yeah it show that as the slope is increased the faster the ball will be and faster the average velocity will be.
** How do you think ave velocity is related to slope? **
You can see that the speed of the ball is increasing and thus the avderage velocity is increasing.
** Speculate on why ave velocity changes with slope. **
I believe the adding of domino's
** How could you test your speculations? **
Well if the speed keeps increasing then it shows at some point research must become valid.

about 45min to and hour

using the timer and computer is a little hard to get used to.
&#Very good work. Let me know if you have questions. &#
