New lesson: add a dielectric to a capacitor held at constant potential difference. Capacitance increases. Charge increases. Net electric field does not change at all. Bobby asks how, and answering him is the whole video. youtu.be/PiVyi7854eY #iTeachPhysics #Physics #Science #EduSky #APPhysics

Aluminum foil, printer paper, a dictionary, and 120 pounds of mass. That is a real parallel plate capacitor. The paper is the dielectric and has to be wider than the foil so the plates never touch. Reads 11.73 nF. youtu.be/Nev4F_QR03A #iTeachPhysics #Physics #Science #EduSky #APPhysics

Common misconception: constant speed in a circle = no acceleration. Wrong! 🔄 Velocity is a vector. Direction always changes, so velocity changes, so there is centripetal acceleration! youtu.be/esf_5HGEbBs #iTeachPhysics #Physics #Science #EduSky #CentripetalAcceleration

I ran out of weights. Plus, it took me 30 minutes to perform the whole experiment when taking all the weights on and off each time. Another fun observation, I left all the weights on for 24 hours and then took new measurements. As you can imagine, the capacitance of the capacitor increased again!
