Day 95: (Area Under F vs. x) vs. velocity

2014-03-06 08.32.21

I missed pictures for the Area vs. change in height lab, but here’s from last year and here’s my writeup for the entire 5 days. Today we collected data to see how the area under the force vs position graph (still haven’t named it…) correlates with velocity. Results below. When students graph A vs. v, it is usually either non-correlated (a variety of possible errors) or, more often than not, pretty obviously not linear. When they linearize it as A vs. v^2 it turns out nice, as shown.
