Blog 8: Disc Sapce

I was working on my computer this weekend.  I had plenty of review to do to prepare for semester exams and spent a lot of time online.  However, everyone needs a break and after a couple of hours of working, I took one myself.  I just searched around my desk and I saw a small disc, the kind used in the mini DVD video cameras.  It contained a video that me and my friends took early in the first quarter for a class project.  After watching it and enjoying a good laugh, I put in a game disc to play a little video games.  I noticed that once I closed the tray my computer's fan began working harder and my computer got hotter.  I realized that since I inserted a bigger disc it had a higher moment of inertia due to its mass and distance.  This meant it required more energy to spin than the mini DVD disc.  Due to its bigger moment of inertia, my computer eventually returned to normal since it also takes more energy to stop the disc spinning.
