Physics 11 – Today the students had their first constant acceleration “equation” quiz. I tried to incorporate some smart questions into it. The first question is “low floor”. Everyone should have success with it. The second question is a boilerplate physics 11 question that the students are expected to be proficient at. The third question is designed to reveal a common mistake. Students will be tempted to use the d=1/2(vi + vf)t equation, using vo = 0. This turns a constant velocity question into one that (mistakenly) has acceleration. We went over the quiz and several students made this mistake. I wonder if hammering on this mistake will prevent it from happening… No, it won’t be it will hopefully reduce its frequency.
