A note on frequency

As you are all going through your write-ups for Lab 2 be very careful when you are talking about or calculating frequency. Frequency can be expressed either as Hz or as rad/s...and you need to be consistent in the way you report frequencies in your report. I would say it would probably be best just to report everything as Hz, but just be sure what you measured experimentally using the FFT and what your model calculates have the same units.
