So we didn't do to much today. We spent the majority of the beginning of class going over the Energy Practice Problems worksheet. Then while questions were taken and answered, the rest of the class began work on the Energy Test Review that is due tomorrow. As for other assignments, windmills are due in 30 days! So time to get cracking on those. I would have to say nothing truly interesting occurred today in class. We did our usual Physics Business!
The question of the day is not an easy one for me.
Qod: How does the height that a pendulum rises to relate to the maximum angle that it makes with the vertical?
Well, if I'm correct, the diagram for this features a sphere being held by a rope, and then the rope is given a force to cause the pendulum to swing. The sphere goes up to form a right triangle with the vertical. The height is the length of the rope that is below this right triangle in the diagram. The total length of the rope is labeled as L and the remaining length of the rope is labeled as Lcos(theta). So the maximum angle reached by the pendulum relies on the height to determine it.
I hope this is right, I haven't exactly grasped this concept, but like many of my other physics friends, I will be making my way in early to talk to Mrs. Coats-Haan. So see you there and Stay Classy!
