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 steepest ramp will require the least time
As slopes increases will time intervals increase, decrease or show no pattern?
they would be increasing as slope increased

Do your results support or fail to support your hypothesis about increasing or decreasing times?
supports it because the ramp got steeper the times got faster
How do you think ave velocity is related to slope?
as slope increases the velocity of the ball also increases
Speculate on why ave velocity changes with slope.
gravity
How could you test your speculations?
make ramp vertical and see where the ball goes
Your data look good.
After the due date we will be discussing this experiment further via an online forum.
