Short Wednesday

Today, only B and E Blocks met due to the early release. Intro Physics took the period to continue working on their universal gravitation problems. A lot of the issue I'm seeing with people's work centers around errors in transcription of data and calculator-use errors. Make sure you know how to use your calculator very well! You should have no difficulty working with scientific notation, order of operations or basic functions of any type. If you are still having problems, make sure you see me for help. Tomorrow, we'll go over these problems and take a deeper look at gravity and the concept of weight and free fall.

Honors Physics began a lab investigation for static and kinetic friction. We discussed these two types of friction before beginning and students started to collect data, which will continue during tomorrow's class. We will compare static friction (maximum) with kinetic friction and discuss why F_s,max is always greater than F_k and the meaning of the coefficient of friction during our lab discussion on Friday.
