Which object did you choose and what were the three positions and the three clock times?
answer/question/discussion: ->->->->->->->->->->->-> :
I chose the pendulum.
Clock time: 40.578 Position: 6”
Clock time: 40.906 Position: 13”
Clock time: 41.125 Position: 17”
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: ->->->->->->->->->->->-> : I think that it would be possible to estimate positions within one-half inch and clock times within .5 seconds. I think that this accuracy would be possible given the speed of the roll of tape/pendulum, which both seem to be moving quite quickly.
• 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: ->->->->->->->->->->->-> : We could use the position of the pendulum versus the position of the tape to determine whether or not the tape is speeding up or slowing down.
• 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: ->->->->->->->->->->->-> : In this instance, we can use the clock and ruler to find an average of where the pendulum should be, assuming that it is moving at a steady pace. If the pendulum is speeding up, it will be further along the ruler than the average tells us it should be.
