Rate of Change in Calculus In case you're in Calculus and wondering how all this rate of change stuff is different now from what you remember from last year (you remember pre-calc perfectly, right?), this video is for you.

02-Average Rate of Change

hangtime — Fri, 06 Mar 2020 22:25:16 +0000

Average Rate of Change of a Function This video covers the most common type of rate of change problem, where they give you a function and ask you to find the "average rate of change on the interval [a,b]." In other words, they want you to find the average Y value of a function between two values of x (or t or whatever the independent variable happens to be).

01-Rate of Change of Line Is Just Slope

hangtime — Fri, 06 Mar 2020 22:22:43 +0000

Rate of Change of Line Is Just Slope In Algebra, they'll often give you problems - word problems usually - where if you distill it all down, the problem basically gives you the equation of a line and asks for the "rate of change" of some quantity. When in doubt, it's probably the slope (or whatever number is in front of a variable).

Average Rate of Change of a Function secant line on [a,b]	This is a very specific topic where you're told to find the "average rate of change of the function on the interval [a,b]." What that means in English is "plug and chug into your average value formula." And hey, why not find the secant line between those two points while you're at it?

05-Angular Momentum and Work

hangtime — Fri, 20 Dec 2019 23:24:09 +0000

Angular Momentum and Work This is a problem you see in lots of physics classes, sometimes involving astronauts or satellites attached by a tether. It turns out that in angular momentum problems, angular momentum is always conserved, but energy isn't. And in a surprise twist, in this problem kinetic energy actually increases! What the what?! That's work, my friend!

04-Kids Move From Center of Platform To Edge

Kids Move From Center of Platform To Edge In this problem we look at a classic piece of playground equipment which - like so many of the greats - is pretty hard to find these days, probably because it was too dangerous. But they were all over when I was a kid in the Midwest and they were AWESOME! A great way for kids to learn about centripetal forces, dizziness, the gyro effect, and even negotiating with your friends and their parents to see who was going to push.

03-Projectile Sticks to a Door

Projectile Sticks to a Door Every book has some version of this problem: sticky projectile collides with a rod that's hinged at one end and you figure out how fast the rod rotates. What a lovely way to combine linear and rotational motion! Maybe your teacher will put it on your test!

01-Overview of Conservation of Angular Momentum

hangtime — Fri, 20 Dec 2019 23:05:55 +0000

Overview of Angular Momentum Angular momentum is pretty straightforward except for one little detail: it's kind of funky that you can calculate the angular momentum of an object that's moving in a straight line. Like you could willy nilly calculate the linear momentum of the next jogger you see run past you. Even crazier, since the jogger ins't rotating, you can pick any axis you want, potentially making their angular momentum HUGE if you pick an axis a block away. This video explains that.

Angular Momentum: L=Iω, L=mvr	Angular momentum is a lot like "regular" momentum: it's conserved. And bizarrely, even an object moving in a straight line has angular momentum. Crazy!
