Wow this was such an amzingly simple way to introduce the topic. Our professor directly started with the formula and I didnt understand anything. But now I did. Thanks prof Matt !
If we use a polar coordinate system whose origin is either 1) moving with uniform velocity or 2) accelerating or 3) itself moving around another fixed point, can we use Newton's second law in the r hat and theta hat directions. I suspect we can still do so in case 1) but not if it's accelerating in 2) and 3). If not, how would we deal with such a system with an accelerating origin: I'm thinking something like a spinning ride itself on a carousel. Hopefully you can comment on this. Thanks.
"Typically" we draw it relative to the positive x-axis, but not always. To stay organized, you should always define the angle relative to some coordinate system, but you can decide which axis to use. Cheers, Dr. A
