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

This data shows the amount of time it took for the ball to reach the bracket from rest on a ramp 293mm long with one domino under one side. This data was obtained by releasing a ball, allowing it to roll down the ramp and strike the bracket.

** Do your results support or fail to support your hypothesis about increasing or decreasing times? **
The results do support the hypotheses I stated at the beginning. The greater the slope, the lower the time interval. The lower the slope, the greater the time interval.
** How do you think ave velocity is related to slope? **
I think that as the slope of the ramp goes up so does the velocity of the ball. As the slope of the ramp goes down, the velocity of the ball decreases as well.
** Speculate on why ave velocity changes with slope. **
Acceleration causes the velocity to change faster on the ramps with a greater slope.
** How could you test your speculations? **
Do another experiment.

Good work. Let me know if you have questions.
