Day 114: Student Representation: Modified Momentum Bar Charts

2014-04-20 19.55.37

 

I was grading some formative assessments I gave yesterday and a student drew their momentum bar chart differently. I LOVE that this shows the total momentum of the system as the total area of the bar! This would only work well with equal masses though (which happened to be the case here), as the heights of the bard are the same (on the vertical axis, velocity is on the horizontal axis).
