We began our wonderful Wednesday morning second period physics class by retrieving our Energy Practice Problems (which were also the previous nights homework) and using keys that were placed on our desks to check over our work. We were also given this time to work on our Energy test review guide. We were instructed to ask questions concerning, not only the review guide and energy practice problems, but on the whole unit in general for that was the last time (before the test) that questions could be asked. Various questions were indeed asked, some coming from Emily, others from Ethan and many more. The purpose of today's class was to prepare for our test and not much else was done.
Question of the day: How does the height that a pendulum rises to relate to the maximum angle that it makes with the vertical?
The angle made when it's at its maximum determines the height by the fact that the height is equal to the length of the string - length * cos of the angle.
