Acceleration problems
In class today we did "stand and deliver" for the review questions assigned in class. This took most of the period.
Some things we went over included how to set up the mathematical solutions to physics problems, the conceptual difference between velocity and acceleration and the fact that acceleration can be negative.
As homework, students were assigned the task of measuring their reaction time by dropping a ruler 10 times, catching it, and using the distance it fell in the reaction time equation to solve the problem. Most should get an answer around 0.15 seconds or so.
