Torque: Force at a Distance©01 - WFU Physics

(only one torque internal to the system) so Angular momentum should be conserved. The wheel started at +Linit to the inverted -Linit. The student on the stool (the only other thing internal to the system) went from 0 to 2 Li (to conserve angular momentum). Lecture Example. During lecture I spin three times around on the platform in 3 seconds. ................
