Unit 20 is fun

Wow, circular motion is turning out to be fun – I got 4 hours done tonight, which is about 1/4 of the unit, plus another two hours spent watching relevant Youtube videos.

Tools needed to describe and derive results are basically implicit differentiation, vectors, polar co-ordinates and a bit of logic.
There’s a lot of calculus in here but it’s pretty accessible.

To gain a little intuition into some of the results being derived, I watched some Khan Academy videos – little maths but enough insight for what we’re doing to make good sense.

After lots of important run-up and results, I got as far as deriving acceleration’s radial and tangential components. There’s a whole lot more to come in this unit.

These should provide the background intuition….

I also watched some more serious stuff, which looks at some of the maths in this unit:
