Table 1

Errors were carried through the calculations in Logger Pro by finding possible extreme values using the errors listed in table 1.

Sample Calculation

 Centripetal Force = (Mass*Velocity^2)/ Radius
    = [(0.0117)*(4.29 ± 0.01)2]/(0.53 ± 0.03)
= 0.41 ± 0.03 Newtons

Drag = Tangent(Lead angle)*Centripetal Force
= Tangent(10.0 ± 0.5)*(0.41 ± 0.03)
= 0.072 ± 0.01 Newtons
