  1. Today in physics we looked at some of the blogs we posted on friday for homework. Reviewed how to calcute speed. You take your distance and divide it by your time.

    Reina went to the restroom at 9:19 am
    Reina just got back at 9:22 am

    Units tell us what we are talking about. We are figuring out the speed for 2.8/1.3 = 19.2yds per sec. When you make your graph make sure you put your highest time number. Students that didnt do there graphs will have the apportunity to finish it in class.

    Desired Results

    Trial 1
    Time vs Distance: Your graph should have a curve line going up.
    Valosity vs time: Your graph should have a diagnal line going down.

    Trial 2:
    Time vs Distance: Your graph should have a diagnal line going up.
    Valosity vs time: Your graph should have a flat horizontal line

    Trial 3
    Time vs Distance: Your graph should have a curve line going up but a little decreasing
    Valosity vs time: Your graph should have a diagnal line going up.

  2. My group's graphs were similar to the "ideal" graphs but not quite, probably for several reasons including simply human error. Also because we realized after discussion that some people stopped the stopwatches when the front of the car reached them and some when the back of the car had passed.

  3. Trial 1 was accurate, Trial 2 was a little off, and Trial 3 did not match at all. Only because our numbers were off.

    Well our first trial was not even close to what you had.We belive that it was becuase like in Carmens group stopped the stopwatches when the front of the car reached them and some when the back of the car had passed.
    In our trial two and trial three they were similar as what you had, we think that it was a little different because, some people reaction is different of others and we are humans so we dont always get things right

    For trial one, our time vs. distance graph went up, but not in a curve. For the velocity vs. time graph, it went down in a somewhat zigzag pattern.

    For trial two, the times vs. distance and the velocity vs. time graphs both were quite on the track of the desired results.

    Trial three was a little off, but had the concept of the desired results.
