q2 i? Despite noise from the slope calculation, the direct comparison of ma(t) with FNET(t) is compelling and serves as a visual connection to Newton's Second Law. → Barber et al. 2007

Figure 3 overlays the student's mass times the video-derived vertical acceleration with net force vs. time, the latter obtained by subtracting the student's standing weight from the force-plate reading. The authors describe the comparison as "quite compelling" despite large noise.

"Although the “noisiness” from the slope calculation is large, the direct comparison is quite compelling and serves as a direct visual connection to Newton’s Second Law"
