Today’s Zoom meeting at Noon
This meeting is optional, but I’ll be online if you have questions. Log into Zoom and use the Meeting ID 569-283-4396.
Quick internet access survey
Please complete this short survey to let me know about your internet access. This will help me know how much I can depend on your access to this website and the resources I share here. All answers are anonymous.
New online homework system
While homework is not required, I have set up an account with TheExpertTA.com to provide practice problems that are graded as you work them, along with tips (some of my past students have said many of the tips aren’t that helpful, but they are there. TheExpertTA is generously providing free accounts for the rest of the semester due to the COVID-19 crisis.
You can sign up for the class here: http://goeta.link/USB06CA-51F289-21B . Email me if you have troubles logging in, and hopefully we can work it out.
Learning objectives
Today is mostly about learning how to use the online resources on Rotational Kinematics and Torque & Angular Acceleration. We have addressed these topics in class, but I want you to get familiar with online system, including the Flipping Physics videos and TheExpertTA problem sets.
Today’s problem set
- Log in to TheExpertTA to find today’s online problems.
- If you would like to solve problems from your book, I’ll be listing them here shortly.
Online simulations
Southwestern College
A great collection of rotational motion simulations on the same page.
Phet
PhET provides a great simulation to experiment with rotation, torque, and moment of inertia. This version runs with Java only, so it won’t run on phones. If Java is not installed on your computer, and you wish to install it, instructions are here for Macs and Windows.

oPhysics
This simulation allows you to change force, radius, and mass, then watch the calculated applied torque and resulting radial acceleration.
