Today’s lecture in intro mechanics is a whirlwind survey of vectors. While I struggle to clear my head enough to be able to teach this stuff, here’s a Dorky Poll to pass the time:
This is a strictly classical subject, so please choose only one.
Today’s lecture in intro mechanics is a whirlwind survey of vectors. While I struggle to clear my head enough to be able to teach this stuff, here’s a Dorky Poll to pass the time:
This is a strictly classical subject, so please choose only one.
Personally, I prefer ECEF or ENU, depending on the problem.
Parabolic, for the Stark effect.
I usually don’t have to worry about a radius, but spherical is the only way to go – stereonets rule!
In the interest of full disclosure, I’m a structural geologist and a fondness for such things is an occupational hazard.
Though usually I work in 2 dimensions and let the contractor sort out the 3rd (as there are standards that govern it they can’t really do it wrong).
You missed an option: I object to the poll, because I have the sense to pick a coordinate system appropriate to the situation :-P
Eddington-Finkelstein-coordinates of course!
You definitely want to use spherical coordinates when doing projectile motion with a = -g j-hat …
I object to this poll because the radial coordinate in cylindrical geometry is _s_, not r.

How to Teach Relativity to Your Dog is published by Basic Books. "“Unlike quantum physics, which remains bizarre even to experts, much of relativity makes sense. Thus, Einstein’s special relativity merely states that the laws of physics and the speed of light are identical for all observers in smooth motion. This sounds trivial but leads to weird if delightfully comprehensible phenomena, provided someone like Orzel delivers a clear explanation of why.” --Kirkus Reviews "Bravo to both man and dog." The New York Times.
How to Teach Physics to Your Dog is published by Scribner. "It's hard to imagine a better way for the mathematically and scientifically challenged, in particular, to grasp basic quantum physics." -- Booklist "Chad Orzel's How to Teach Physics to Your Dog is an absolutely delightful book on many axes: first, its subject matter, quantum physics, is arguably the most mind-bending scientific subject we have; second, the device of the book -- a quantum physicist, Orzel, explains quantum physics to Emmy, his cheeky German shepherd -- is a hoot, and has the singular advantage of making the mind-bending a little less traumatic when the going gets tough (quantum physics has a certain irreducible complexity that precludes an easy understanding of its implications); finally, third, it is extremely well-written, combining a scientist's rigor and accuracy with a natural raconteur's storytelling skill." -- BoingBoing
