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

I got this data by setting up the track with one domino on one end and timing the ball until it strikes the bracket on the bottom end, then I reversed the setup and timed it.

I placed two dominoes under one side of the track, and timed the ball until it stopped at the bottom, then I reversed the setup.

** Do your results support or fail to support your hypothesis about increasing or decreasing times? **
These results support my hypothesis because the time intervals are indeed decreasing as the slope is increased with the dominoes.
** How do you think ave velocity is related to slope? **
The average velocity is related to the ramp slope because when one end of the ramp is raised, gravity has more effect on the velocity of the ball.
** Speculate on why ave velocity changes with slope. **
I think gravity increases the potential energy of the ball when the slope gets steeper.
** How could you test your speculations? **
By calculating the average velocity of the varying slopes of each ramp and comparing them.
