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? **

I think the steeper the slope the less time you will need for it to travel the distance.

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

Increasing

** Your report of 5 trials each way for 2 dominoes **

I was thinking that as the marbled rolled farther it was picking up speed.

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

Yes the results do support the hypothesis because as the slope gets steeper the marbel travels over the board in less time.

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

With greater slope comes greater average velocity. If we find that an object has a greater average velocity we find that it has a greater speed and with more slope comes more speed.

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

I am thinking that with greater slope comes greater speed and with higher speeds comes greater velocities.

** How could you test your speculations? **

Continue to add dominos or get a heavier object and try the same experiment on it.
