Today in Physics we checked our Gravitational U problems with Mr. Ebersole.  After we felt confident in our abilities to master the questions, we moved on to the lab for the day, Conservation of Energy with Hall’s Carriage Lab.  Mr. Ebersole made sure we sat down and read the lab through before we started because our class did not follow the directions the day earlier.  The lab took the rest of the period and Mr. Ebersole stopped us a few minutes before the bell rang to remind us of our homework.  We need to turn in the Conservation of Energy Simulation lab tomorrow.  On Tuesday we need to have implemented our conservation methods on the electric meter.  On Wednesday the lab write-up for the lab we completed in class is due.  Finally, there are 36 DAYS UNTIL OUR WINDMILL IS DUE!!!!!!!

Qod answer:

When the object is at a height of zero and not in motion or when the work (W) is in the opposite direction.

Today in Coats-Haan 3rd period class, we checked the homework assigned to us over the weekend (Pg. 189 #'s 1-8). Coats-Haan generously answered any questions that we asked her. We then continued with our energy notes that we began on Friday. Before we started the notes, we watched a video of a German who went down a slip-n-slide and ramped off into an inflatable pool. We discussed how this was impossible to accomplish without video editing. Continuing our notes, we attentively listened as Coats-Haan taught us of gravitational potential energy, path independence, and conservation. We completed some example problems to help us better understand the concepts. We were handed out a pair check to be completed in class, and finish for homework, if not completed in class. We also took out page 111-113 of our Physics manual, which is to be completed by Friday. Our homework for tonight is page 189, numbers 12-18 in the textbook. We also have to complete the Home Energy Survery by tomorrow and continue to work on our windmill project. Overall today happened to be another tremendous day in Coats-Haan 3rd period class. The same probably could not be said of the other classes, but that is because they just lack the diverse characters in our class and the fact that no other class has a Team I <3 Life.

QOD: Some problems with the "crazy insane water slide" is that he would not have been able to build up enough energy to get up the ramp and reach the height that he did when he finally did ramp off the slide. Also, if the man had been able to get up the ramp, he would have hit the pool so hard with such a velocity that he would have serverly injured himself.
