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 with the steepest ramp should have the least time.
** As slopes increases will time intervals increase, decrease or show no pattern? **
I think the time intervals will be decreasing.

I set up my ramp with a domino underneath one end and rolled a ball down measuring the time of release and the time the ball hits the bracket on the other end.

The first 5 numbers were measured with 2 domino's under the right side of the ramp and the second set of 5 numbers were measured with the domino's under the left side of the ramp. The measurements are from the point of letting to until the ball hits the bracket at the other end.

** Do your results support or fail to support your hypothesis about increasing or decreasing times? **
Yes I believe so. The larger the slope, the faster the ball moves through the same distance.
** How do you think ave velocity is related to slope? **
The average velocity should be greater if the slope of the ramp is increased. The faster the ball moves down the ramp, the greater average velocity and slope.
** Speculate on why ave velocity changes with slope. **
The angle of the raised end causes the average velocity to change with the slope. The higher the angle, the higher the average velocity and slope.
** How could you test your speculations? **
You could do another experiment with different angles and rolling different side balls and see if the evidence matches this. If it does, we could conclude that these explanations are valid.
