Notes and sample data for PHYS 141 friction experiment.
S Friction
Ramp angle calculated from geometry= 13.9°
iOLab Masses
M1 = 201.7g +/- 0.2g and W1 = 1.98N
M2 = 203.4g +/- 0.2g and W2 = 1.99N
Since theta = 13.9° we get.
Fg1 = 0.48N
Fg2 = 0.48N
Normal Forces are.
N1 = 1.92N
N2 = 1.93N
From F = ma we get the accelerations without friction as.
a1 = 2.379m/s^2
a2 =
