What factors do you think ought to be considered?

Glad to hear you're able to catch up on the material. Prof. Lewin does an amazing job, and if you watch his lectures, you see almost the exact thing we do in class (at least in this unit)... he's as good, if not better, than anyone I've seen in lecturing about rotational motion and angular momentum.

I'm betting he followed the direction in this post from our forums: http://www.aplusphysics.com/forums/showthread.php?15-Embedding-formulas-into-your-posts.

Great post willorn! By the way, if you're interested in superconducting magnetic levitation, it just so happens that I've managed to pick up a disc of Yttrium Barium Copper Oxide... we could videotape a demonstration and explanation for the Physics In Action podcast -- just need to pick up some liquid N2, which isn't tough to do with a bit of advance planning!

Awesome analysis and a creative way of applying what we're learning to a VERY big scenario. Well done! :wave)

You're not alone in your thoughts. Our unit on rotation and angular momentum will be, by far, the most difficult of the entire mechanics course. Not only is the material new, it utilizes calculus you're just learning, and it is by no means intuitive -- in many cases, it's just the opposite, actually (angular momentum is just one of those things that doesn't really fall into our everyday conceptualization easily). Very shortly, as we get into the heavier stuff, we'll slow down the amount of material being thrown at you each day and balance it with lots and lots of practice so you start to feel more comfortable with it.

Great find Alex -- these are the videos I highlighted in your independent work unit. Our version of AP-C physics is, in many ways, based on Dr. Lewin's lectures. In creating the course format, I relied heavily on his lecture series myself. Good stuff, and a highly entertaining professor. His unit on rotational kinematics and angular momentum are by far the best I've seen, so you'll see our work in class highly correlated with his videos over the next couple weeks!
By the way, for those of you with iPods and iPhones, these online lectures are available for free download to watch on your iPod through iTunes...

I've never considered the physics of a dragon before... They'd make great study subjects for kinematics... or even thermodynamics!!!
-
Can you elaborate on why you think you should go higher? What factors play into the height of your jump? How could you analyze these factors using what you know about kinematics, dynamics, momentum, impulse, and conservation of energy?
-
I'm glad you enjoyed the unit... is it something you'd like to do again later in the year?
-
Would love to hear about physics of Jai-Alai!!! :labmate)

THAT'S what I'm doing wrong when I go golfing... more plaid!

Easy enough to fix up... to embed a movie, all you have to do is copy the regular youtube link (not the embed link). Then, in the APlusPhysics editor, click the movie icon and paste your youtube link in there. The editor will take care of the rest!

(To make your equations work, I just added the tex and /tex tags around either side of your code. Details available here: http://www.aplusphysics.com/forums/showthread.php?15-Embedding-formulas-into-your-posts)

You just needed a space after the [tex] tag... least I could do was clean that up after your argument with the login timeout earlier tonight!
