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? **
I would assume the steepest ramp would take the least 'dt
** As slopes increases will time intervals increase, decrease or show no pattern? **
decreasing

These are time interval for the steel ball rolling down a 247mm ramp elevated on one domino. 5 times in each direction

** Do your results support or fail to support your hypothesis about increasing or decreasing times? **
These results support the hypothesis
** How do you think ave velocity is related to slope? **
Average velocity is linearly related if the system is frictionless. At the level of precision we are applying it is a linear relationship. The closer to vertical the ramp would become the less impact friction would have because the vector applying force to the ramp reduces at a logarithmic rate
** Speculate on why ave velocity changes with slope. **
The greater the slope the larger portin of a gravitational vector goes toward moving the ball down the ramp.
** How could you test your speculations? **
By repeating the experiment with a higher order of precision and graphing the results

Very good data and responses.
