Note: Never trust Web forms. Compose your answer in Notepad or a word processor, saving it every few minutes, then copy and paste it into the box.
Power could surge, your computer could malfunction, in any of a number of ways the work you put into this form could be lost. Compose it elsewhere and keep
a copy. (However you should understand that if a Web form gives you a confirmation, then it has almost certainly worked correctly and sent the data to the
appropriate file. It's still a good idea to keep a copy of the confirmation.)

In the space indicated below report your data. State exactly what was measured, how it was measured, how accurately you believe it was measured and of
course what the measurements were. Try to organize your report so the reader can easily scan your data and identify any patterns or trends.

Using your data determine how fast the object was moving, on the average, as it rolled down the incline. Estimate how accurately you believe you were able
to determine the object's average speed, and give the best reasons you can for your estimate of the accuracy.
your brief discussion/description/explanation:
Open end propped 3.199498118cm/s
Spine 4.139228598 cm/s
I believe I Was acurate within .01 cm/s.
My reason for using this is that was close to the accuracy differece for my mesurments.

Devise and conduct an experiment to determine whether or not the object is speeding up as it rolls down the incline. If you have set the experiment up as
indicated, it should seem pretty obvious that the object is in fact speeding up. But figure out a way to use actual measurements to support your belief.
Explain how you designed and conducted your experiment, give your data and explain how your data support your conclusions.
your brief discussion/description/explanation:
The experiment I devised was a increasing slope seeing the time differec for each.
Time
Slope 1 1.719
Slope 2 .703
Slope 3 .625
