Meese 2/6

First off, I would like to take this time to applaud the effort of Mrs. Coats-Haan's hard-working student teacher. The sad thing is that I still do not know whether his name is pronounced like Eversol or Ebersol, but I digress. Today in 3rd period Honors Physics, we were greeted with reminding us of the slew of  assignments due this week. The Take Home Energy Lab is due on 2/7, the Lab Report is due 2/8, the Energy Test is 2/9 and the Windmill Project is due 3/9. While looking at thge board it is also quite easy to see that the homework tonight was page 193 #'s 63-67. To start off the physics portion of the class, we went over the homework from the weekend, which was #'s 55-60 on page 192 (I think). Our class is so intelligent that the only one that we could not figure out was by far the most difficult of the bunch, the dreaded number 60. Our beloved student teacher worked through number 60 beautifully, so that even I could understand it. The class then proceeded with a POGIL on spring constants in relation to energy. The POGIL was fairly involved but it was no match for my team of geniuses. We worked quickly and efficiently on the POGIL and were able to finish it in time to further discuss our windmill project. And believe me, as 3rd period Honors Physics, we definetly "stayed classy" throughout the remainder of our day.

QOD: The definition work = force x distance is not always true because this equation implies that we do work every time we exert a force, which due to the phenomenal teaching of Mrs. Coats-Haan we understand that that is not a true statement.

2/6 qod

Why is the definition "work = force x distance" not always true?

2/2 Lee

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.

2/2 qod

Give an example of using the Ui+Ki+W=Uf+Kf equation where the right side would all be zero.

Happy February! 

Give an example of when the work term in the conservation of energy would be positive and when it would be negative.
