ball down ramp

Phy 201

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? **

Time will be the least for the steeper ramp.

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

Time intervals to be decreasing

** Your report of 5 trials each way for 1 domino **

The first 5 times are the time intervals from the top of incine to the bottom.the top five times are from the incline position on the table with the dominoes under theright end. the times on line 6-10 are the times with the dominoes placed on the left end.I would get these times by clicking the timer at relace point and click it again at the instant it hit the bracket.I kind of knew that it would be different because the table I am working on is bowed just a little

Data was recorded the same way as before but this time the incline was raised using two dominoes instead of 1

Data was recorded as above but with 3 dominoes instead of 2

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

The data supports me. The time intervals decrease and the steeper the incline the faster the ball gets there

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

You increase the ramp slope and the vAve increases. For each time I raised it by a domino it didn't double. The higher I increased the slope the vAve were getting closer together

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

I think the vAve increases with the increase in slope you have less drag or friction.

** How could you test your speculations? **

If you continue to raise the slope to a point of say 80degrees it would almost be like a free fall
