ball down ramp

Your work on ball down ramp 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 steepest ramp with have the least interval.

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

i would expect the time interval to be decreasing

Your report of 5 trials each way for 2 dominoes

i was thinking that the ball seemed to be rolling fairly slow coming out with a result being close to 1.5 each time.

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

the results supported my hypotheses that the higher the angle became for the slope, the time interval would decrease

How do you think ave velocity is related to slope?

the average velocity increases as the slope of the ramp increases

Speculate on why ave velocity changes with slope.

the ball travels at a slower pace when the slope is not as high, causing the velocity to decrease. but when the slope increases, the velocity does too.

How could you test your speculations?

the experiment shows that the ball traveled faster the higher the slope proving it has a higher velocity, while the ball traveled slower the lower the slope proving it has a lower velocity.
