Day 116 – Change in Momentum


Physics 11 – Most of my classes were able to finish their analysis of the colliding cart. I can tell that many of the students are getting really comfortable with moving their concepts and models in and out of different situations, which is really cool.

From their analysis, students reasoned that the “impulse”, or force acting over a period of time, was equal to the change in momentum. We didn’t get into error analysis really, our class time was pretty short today. I might try to have them do another momentum lab to study the conservation of momentum. I do want to have another formal lab report written and graded this time. On the other hand, I am constantly aware of time constraints…
