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 **

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

The steepest ramp will have the least amount of time.

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

The time intervals would decrease.

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

Yes. The dominos that were three stacked on one side had the lowest time intervals.

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

The pendulum is related to the slope of the ramp because the length of the full cycle of is close to the size of the ramp.

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

The further the ramp is from the center of gravity, the faster the average velocity.

The center of gravity is part of the ramp. However your intent seems clear and correct. I think what you mean to say is that further one end is above the other, the greater the average velocity.

** How could you test your speculations? **

This is verified by when the ramp is leveled out and there is no incline.

90 min.
