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 would be least for a ball to roll down the steepest ramp.
As slopes increases will time intervals increase, decrease or show no pattern?
The intervals would decrease as the slopes increase.

While performing the trials I was concerned with clicking the timer when it actually hit the bracket and trying not to click it too soon in anticipation of the sound. This is a problem I had during my practice runs.

Do your results support or fail to support your hypothesis about increasing or decreasing times?
My results support the hypothesis that the steeper the slope, the faster the time.
How do you think ave velocity is related to slope?
I think the average velocity of the ball is inversely proportional to the slope of the ramp.
Speculate on why ave velocity changes with slope.
I suppose that gravitational forces are stronger from a higher position and cause the object to pick up speed.
How could you test your speculations?
You could plot the height of the plane against the average velocity on a graph to illustrate the relationship.The line would indicate that when the ramp height increases, the velocity decreases.
This looks very good, as do the other labs you have submitted to date.
After the due date we will be discussing this experiment further via an online forum.
