We started the period with the quiz on WS 2. We also graded quiz 1. We continued our discussion of free-falling objects, this time focussing on position-time, velocity-time and acceleration-time graphs and the conditions that produce terminal velocity. To go along with this, we watched the Mythbusters episode about the penny falling from the Empire State Building. At the end of the period we discussed average versus instantaneous velocity. They are both calculated the same way, the main difference is that an average velocity is calculated over a large time period. The instantaneous velocity is a velocity of an accelerating object at one brief moment in time.
HW: Finish WS 3; Unit Test on 11/10
