Эта женщина - шикарный учитель физики. Меня и восхищает, как именно она преподносит материал, и в то же время я испытываю огромное сожаление из-за того, что она не преподает у нас в России. У нас в школе она была бы ограничена «открываем учебник на странице 37, читаем параграф 5», но бьюсь об заклад, даже в этом случае она бы что-нибудь придумала.
Наглядное объяснение почемув штатах техаские учебные заведения оценивают очень низко. Это же пример из программы начальной школы. Они бы ещё покащали воронку с водой и указали бы на сторону её вращения как результат вращения Земли. Всем добра
Shes amazing; there's a reason her class always has the highest exam grades. One of the other profs at TAMU wrote the textbook they use for the physics classes and her averages are still higher than his lol
If you don’t understand, when she flips it upside down, the direction of angular velocity reverses, and since there is no friction to cause an external torque, she rotates in the same direction as it was initially spun. Combined, their angular momenta is the same as before.
You need to find the schools appropriately so teachers can have all the equipment she has access to. As a teacher in an inner city school, we don’t even have a lab. So how am I supposed to do all these cool experiments?
My physics prof did this in our class for college, he's the reason I l fell in love in Physics because he teaches so enthusiastically and makes Physics fun
My physics prof did this and she is the reason I fell in love with her I was 12 when we met and she was 32 and now we have been married together 42 years
Angular momentum, which is a feature involving the speed of rotation, the mass of the wheel, and the distribution of the mass, is a characteristic of rotating bicycle wheels. Wich is why she spins with the wheel spinning upside-down but not upright
@@NatFrog154 wheel is spinning one direction when it's upright, let's call that "1 unit of rotation", then she rotates it and not it spins opposite direction, let's call that "-1 unit of rotation" (negative because it's opposite). Now, because of some physics stuff, rotation must be conserved, but here she suddenly switched 1 unit rotation into -1 unit of rotation, physics makes it back to 1 unit by rotating her 2 units of rotations, so 2 + (-1) = 1 again. It's called Law of conservation of Angular momentum. Angular means speed in degrees and not meters/miles and momentum means it also depends on mass, this is why even though she has 2 units of rotation, she doesn't rotate as much, because she weighs more than a wheel
When the wheel spins one direction, it has angular momentum which has to stay constant. When she flips the wheel it’s negative, so no longer constant and an angular momentum is induced on her body to keep it constant.
Ive had a few teachers like her. Theyre the absolute best, they make any subject seem fun and useful. Theyre kind of teachers that you wanna work hard for even if you started out not liking the subject, and you wanna make them proud when you get older. the ones that keep you visiting the schools even when youve graduated or the ones you remember and quote even years into your adulthood. I Hope she lives fruitfully ❤️
@@lexamikoff ну она молодец, впрочем за ее зарплату что так не радоваться , это наши педагоги идут на вторую и третью работу, а потом с утра не развитым личинусам с кислой и уставшей миной на лице
@@АлександрКирпиков-и1х ну уже давно не так всё однозначно с оплатой труда педагогов у нас. Подобные ей профи очень востребованы в частных учебных заведениях, где платят очень даже достойно. Но основная масса провинциальных муниципальных, конечно, увы..
Idk either but I’m guessing bicycle wheel was spinning one way causing it for her to spin one way really fast and the other slower and idk so can someone correct me
Conservation of angular momentum. The total amount of spin must remain constant without outside force. The bicycle wheel is spinning quickly let's say clockwise, but then when she changes it to counter clockwise, you need some human rotation to counteract the directional change in spin caused by flipping the wheel. There are more rigorous scientific definitions to do with moment of inertia, angular velocity, conservation of angular momentum, etc, all things you learn the math behind in an intro college level physics class, but the concept is understandable to everyone.
@@crystal..doesedits I get that... For me it was the number of "Introduction To (insert science/engineering topic here)" class names. There are PhD level Intro classes, there was one series where it was called Intro I, Intro II, and Intro III. Like, THE THIRD CLASS IS NO LONGER THE INTRO TO THIS TOPIC! Anyways, back to the physics, if there is something you aren't understanding with my explanation, I'd be happy to rephrase or answer questions.
