Circular Motion: Torque, centripetal force, and gravity

Reading
BJU book: Ch. 7 "Circular Motion"
AP students additional reading: Princeton Review "Uniform Circular Motion" - read applicable sections. 

Topics
​We will spread this topic over two sessions:
  1. Rotational equilibrium and torque problems
  2. Centripetal force and gravity problems

Labs
Memo: 2020-2021 labs will include hands-on and virtual, and may vary as the Covid-19 situation changes. 
  • ​Rotational Equilibrium lab is our regular go-to lab, but there are numerous virtual labs also which cover the topic, as well as labs you can do at home. We'll decide when we get here.

YouTube is full of Perpetual Motion machines. They are all FAKE.  They generate millions of 'hits' and make money for people. Here is one of my favorites...  The video on the right shows how it's 'faked'. 
Summary
Our study of "Circular Motion" is divided into two sections, 1) Rotational Equilibrium & Torque, and 2) Centripetal Force & Gravity
