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.
