    Percent error


    The method used to calculate the distance a person can jump using a stop watch has such a high percent error due to multiple flaws and minor problems we ran into. For instance most students are inept to using a stop watch correctly so it is highly probable that the times we recorded were incorrect and/or flawed. Also the measurement taken by the ruler could have been wrong due to faulty eye sight or not having the ruler at the correct angle.

    Young physicists at IHS have calculated the acceleration due to gravity. How did they do it? By putting together a lab where they calculate the amount of time it takes for a ball to hit the ground from a set distance they can find the acceleration due to gravity. If one can find at least three out of the five variables; Initial velocity, Final velocity, Acceleration, Distance and Time.

    We knew the initial velocity was zero, and the distance we measured, which was 260 centimeters (or 2.6 meters) and it took an average of about .67 seconds to hit the ground. The acceleration due to gravity according to this experiment would be 11.6 m/s2 with a percent error of 18%.

  3. I'm looking foward to a busy year full of my my favorite (and not so favorite) things. This includes reading of course, which I do almost constantly. One book I want to read this year is The Hitchhiker's Guide to the Galaxy. Also, I plan on auditioning for the fall and spring plays at my school and the school musical. Overall, I'm going to have a ton to do this year.


    One of the many classes I'm taking this year is (obviously) physics. I decided to take physics mainly because it seemed interesting and I want to take at least four sciences in high school. This year I hope I learn a lot about how the world works. I'm looking forward to having fun in science this year.
