  1. Physics students in Mr. Fullerton's class conducted an experiment determine the acceleration due to gravity in a free falling object. The students ran through several trials utilizing a ball dropped from a controlled distance, 2 meters, and used a timing device to record the dropped ball's velocity. The students then calculated the average time, finding it to be .563 seconds. With this information in mind the studnets were able to calculate the acceleration due to gravity. Here is the table of variables the students utilized to find the acceleration:

    Vi = 0 m/s

    Vf = Not needed

    A = ?

    T= .563s

    By using the kinematic equation a=d/t, the students came to a final acceleration of 7.105 m/s^2. In comparision to the universally accepted value of 9.81m/s^2, the final acceleration was invalid due to a percent error of over 27%. Many variables can attribute to the large margin of error, including mechanical error in part due to the stopwatch.

  2. Hi I'm Roxy and I'm a senior. I run cross country and do art (clay sculpture and pen are my favorites). This summer I took a nap almost every day, watched the first 5 seasons of The Office, and spent alot of my time lifegaurding here at the IHS pool. I like food and nice people and good music among other things obviously but those are the essentials. Honestly I'm not looking forward to senior year too much but am excited for what lies ahead after high school.

    I decided to take phyisics because I was told by many that it's an interesting class and is helpful when applying to college. Its good to get a basic understanding of all the sciences. I know absolutely nothing about physics except that making a tower out of spaghetti and getting it to support a marshmallow is really hard, so I'm excited to see what the class is about. It will be interesting to see how the world around us works.
