I forgot I previously made this SHM @desmos.com comparing UCM, pendulum, and mass on a spring side by side until I was getting ready for class this evening. #iTeachPhysics https://www.desmos.com/calculator/ehmhbbgmhp

Cool, but I always like to show the real thing too! This is one of my favorite Pivot Interactives videos. A similar thing was done in the Mechanical Universe video: https://youtu.be/zfNR3zQyI3E?si=Xb_2vuoelfTx-ZEV&t=404 #ITeachPhysics
I've had kids do video analysis of a similar video, and they noticed that for the pendulum, the horizontal motion graphs have 2x the period of the vertical motion graphs, which makes for some cool discussion about why!

In the UK I had the turntable and the physical reality in front of them is even better than the video (if I may say so 😊)
