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? **
it will be least because it will travel faster and take less time than the ramp with a less steep slope
** As slopes increases will time intervals increase, decrease or show no pattern? **
they would be decreasing
** Your report of 5 trials each way for 1 domino **

its how long it took for the ball to roll to the end of the ramp and hit the bracket. i used the timer to count how long each trial took.
** Your report of 5 trials each way for 2 dominoes **
it took a lot quicker than i thought it would.

** Do your results support or fail to support your hypothesis about increasing or decreasing times? **
yes, it took less time each time i added a domino
** How do you think ave velocity is related to slope? **
the greater the av. velocity, the greater the slope
** Speculate on why ave velocity changes with slope. **
the change in time
** How could you test your speculations? **
by showing my times of my trials with each domino
** **
30 minutes
