Your work on ball down ramp 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 required will be the least for the steepest ramp and most for the shallowest ramp.
As slopes increases will time intervals increase, decrease or show no pattern?
I think the time intervals would be decreasing since it would take less and less time to roll down the whole ramp.

I was thinking that this would probably agree with my hypothesis that the steeper the grade, the fast the ball will roll.

Do your results support or fail to support your hypothesis about increasing or decreasing times?
I believe that my results support my hypothesis. I estimated that the steeper the slope that faster the ball would roll and the less time it would take. In fact that is exactly what happened.
How do you think ave velocity is related to slope?
Yes i believe that the higher the slope, the higher the velocity of the ball. The slope has an impact on the gain of momentum of the ball. The more distance or slope that a surface has, the higher momentum an object traveling on that surface will gather.
Speculate on why ave velocity changes with slope.
I believe it is gravity. The steeper the slope, the more effect the gravity has on the downward momentum of the ball as opposed to just the sitting momentum of the ball.
How could you test your speculations?
attempt to do the experiment in an environment without gravity's affect. A weightless environment would show that an object's weight is merely the act of gravity pulling on it giving it momentum.
