Which object did you choose and what were the three positions and the three clock times?

answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):

#$&* I chose the tape rolling down the ramp in video 3. One point was approx. 7 inches and clock time was 29.3. Half-way point's clock

time was approx. 29.3. The third point observed was roughly 16 inches and the clock time was approx. 29.7.

In the following you don't have to actually do calculations with your actual data. Simply explain how you would

use data of this nature if you had a series of several position vs. clock time observations:

If you did use observations of positions and clock times from this video, how accurately do you think you could

determine the positions, and how accurately do you think you would know the clock times? Give a reasonable

numerical answer to this question (e.g., positions within 1 meter, within 2 centimeters, within 3 inches,

etc; clock times within 3 seconds, or within .002 seconds, or within .4 seconds, etc.). You should include an explanations of the basis for your estimate:

Why did you make the estimate you did?

answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):

#$&* The positions and clock times I observed were a little bit vague, but they seem to be the closest estimates.

How can you use observations of position and clock time to determine whether the tape rolling along an incline

is speeding up or slowing down?

answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):

#$&* Check the clock times with the same positions as the other videos to see if they are less or more than the previous video. Is there a certain formula

How can you use observations of position and clock time to determine whether the swinging pendulum is speeding

up or slowing down?

answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):

#$&* Look at the same positions and look at their clock times in the previous videos and determine whether this observations is slowing down.
