Good work. The units are indeed cm / sec.
There is no need for a table on this experiment.
DESCRIPTION
I used a ball provided with the lab kit as the object to roll. I propped a clipboard up on a book to make the ramp and I used the clock on my computer to time the ball roll since I did not feel my pulse would be accurate enough.
DATA
The difference in height of the clipboard was 1.5 centimeters, the distance the marble rolled was 29 centimeters and the time required for the ball to roll down the ramp was 2 seconds.
ANALYSIS
The position of the object change from release to the end of the ramp was 29cm.
The high end of the ramp was 1.5cm higher than the low end of the ramp.
2 seconds was required for the ball to roll from the top to the bottom of the ramp. (I did the experiment 5 times and each time took 2 seconds).
The average rate with respect to time that the object moved down the ramp is
14.5cm/sec.
(Not sure if I did this right but my calculation was 29cm / 2sec = 14.5cm/sec).
I got confused as to how to do the division “with respect to time”. I couldn’t figure out if that meant that my units needed to be in cm/sec or sec/cm. I looked up my notes from the rates program and I think I interpreted them correctly when I decided to use cm/sec as my units. It is true to say that if the question says “with respect to a certain unit”, then that unit is you use to divide? I hope that question makes sense.
I read in the instructions that you need the values organized in a table. I’m not sure how to make a table out of these values since there’s so little data…
