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 =
