ibpotterhead Posted November 6, 2016 Report Share Posted November 6, 2016 Hi guys, I'm thinking about investigating the effect of surface on angular momentum of a spinning coin. I'll be spinning the coin on various surfaces (wooden table, plastic, cloth etc) and measuring its velocity by using slo-mo camera. Would this be a good IA? All suggestions are welcome, thanks. P.S. I'm in Physics SL Reply Link to post Share on other sites More sharing options...
kw0573 Posted November 6, 2016 Report Share Posted November 6, 2016 It think it's a good topic if you can ensure you are more or less releasing the coin the same way (such as same initial angular velocity). It may also be interesting to first do the investigation on one surface many many times to see if you get a distribution of angular velocities or fairly consistent ones.

cnd4747 Posted November 17, 2016 Report Share Posted November 17, 2016 I agree with KW - interesting idea, but I don't know how you'll guarantee the coin will spin the same way each time. Reply Link to post Share on other sites More sharing options...
Alex Perrish Posted November 23, 2016 Report Share Posted November 23, 2016 Hello guys, i am thinking on doing an investigation on the relationship between magnetic field and electric field... that is... i will be rotating a round metal disc which is electrically charged between a magnet which is highly magnetized.... i will change either the strength of the magnet or the distance o the disk from the magnet which one is better i am confused... or any other variable?
