 Oct 31 awarded Notable Question Oct 22 awarded Popular Question Sep 9 comment Investigation of a pendulum's period, problem creating equation to sum the dynamic velocity the $t=t(\theta)$ is itself an approximating function. Naturally i would expect and approximating function. Seems that it exists from equation $(31)$ in that paper. (+1) Sep 9 comment Investigation of a pendulum's period, problem creating equation to sum the dynamic velocity i would like to know if inverse of this function $t = t(\theta)$ exist or not.

Aug 6 accepted Why do rolling disc (coin) move in circular path? Aug 6 revised Why do rolling disc (coin) move in circular path? added 109 characters in body Aug 6 comment Why do rolling disc (coin) move in circular path? @Ankush The coin is moving in circle means it should be spinning ... with period equal to the period of circular motion. Aug 6 comment Why do rolling disc (coin) move in circular path? $J$ is angular momentum. Aug 6 comment Why do rolling disc (coin) move in circular path? @Ankush since the coin is moving in circle ... something must continuously change the direction of the coin (so that coin follows circular path).

Aug 6 comment Why do rolling disc (coin) move in circular path? and thanks for response!! Aug 6 comment Why do rolling disc (coin) move in circular path? shouldn't this kind of torque make the coin fall? ... it comes towards us. Aug 6 comment Why do rolling disc (coin) move in circular path? could you elaborate a bit please?
