Experiment Teachers' Notes and Sample Data
Part 1
In this example
r
= 0.38 m.
1)
Arc Angle,
θ
= 1.42 rad
2) s
=
r
θ
= (0.38 m) (1.42 rad) = 0.54 m,
theoretical
3) s
= 0.57 m,
actual
4)
In this example the theoretical and actual values of
s
differ by 5%.
Part 2
Students should predict v
T
=
r
ω
1)
The graphs of Velocity vs. Time and Angular Velocity vs. Time appear
to be directly proportional.
