Simple Harmonic Motion - AP Physics Please help Bob the Pendulum by designing an experiment to determine his frequency.

(a) Which the lab tools would be used to help Bob:

Additional masses

additional length of massless chain

meter stick

Photogate

protractor

stopwatch

(b) the procedure for determining Bob's frequency including the measurements used to make, how the equipment will be used to make the measurement and how you'll determine Bob's frequency from those measurements.

(c) Now Bob wants to know which variables affect his frequency. Explain to Bob how one variable could be changed in the experiment, how you would conduct the new experiment and how i would analyze the data.

(d) Bob turned on a motion detector in order to graph his position v. time as he was happily oscillating.
