ball down ramp

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 **

Would like to have feedback. Thanks, Joshua

** Will a steeper ramp give greater or lesser time? **

I think that the interval would be the least for the steepest ramp.

** As slopes increases will time intervals increase, decrease or show no pattern? **

I think that the intervals would be decreasing.

The first 5 time intervals represent the data taken from timing a ball down a ramp going from right to left. The remaining 5 intervals represent the data taken from timing a ball down a ramp from left to right.

It was collected by timing a ball down a ramp from 0 velocity to the end. Using only one dominoe to create the slope.

** Do your results support or fail to support your hypothesis about increasing or decreasing times? **

Yes my hypothesis seems to be correct in that with a steeper slope the intervals got smaller.

** How do you think ave velocity is related to slope? **

As the slope increases(gets steeper)the average velocity increases. When looking at a line on a graph the final velocity increases up the y axis as the slope increases therefore the average velocity increases beccause it follow the motion of the final velocity. In this case.

** Speculate on why ave velocity changes with slope. **

When looking at a line on a graph the final velocity increases up the y axis as the slope increases therefore the average velocity increases beccause it follow the motion of the final velocity. In this case.

** How could you test your speculations? **

Plot the graph of each of the three slopes and use the graph lines in comparison against each other.
