Another lab but with frustrating equipment

We had the Doppler lab. Though, we strangely had a very high percent error despite following the procedure correctly and asking for help to confirm we were doing the steps correctly. I think the problem was starting and stopping the moving little cart, timer (to get velocity), and frequency measuring equipment all at the same time is very difficult to pull off as it requires nearly perfect timing that may be humanly impossible with hands. For instance, stopping be timer too late will lead to the measurement of time being too great which gives a false lower velocity than expected. I think that’s all we did that day.

On a brighter, off topic note, that very old windows XP computer we had to use reminded me of some nice old childhood games on an old windows XP computer that I used to have before it died. Reminds me of when I was a toddler.
