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 shortest time to travel the length of the track

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

the time intervals will be decreasing

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

The data is the time in seccond that it took for the ball to roll from start to finish along the track for 29 cm at the specific slope with one domino.

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

The results supported my original hypotheses. As the slope increased, the time to travel the length of track decreased

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

The velocity of the ball increases as the slope of the ramp increases

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

The greater the slope of the track, the ball obtains more acceleration due to gravity. if the track is flat, there id no acceleration and no movement because the track supplys all the resistance force due to gravity.

** How could you test your speculations? **

We could draw some force diagrams to see what resistance forces are appied by the track and what direction those forces are applied to the ball.
