Video Discussion: The Reality of our First Free Body Diagram

Recommended Posts

Name: The Reality of our First Free Body Diagram

Category: Dynamics

Date Added: 19 November 2014 - 02:55 PM

Submitter: Flipping Physics

Short Description: None Provided

The free body diagram we first learn is not entirely accurate. All of the forces are not drawn from the center of mass of the object. Learn why we start this way and, when we get torque, what the free body diagrams will actually look like.

Content Times:

0:12 Reviewing the first free body diagram

0:39 A more correct free body diagram

1:22 Comparing this approach to the projectile motion approach

1:52 When we get to torque

2:42 The green screen

Thanks for showing the Green Screen setup at the end of the video -- I'm currently working on a basement office at home and am hoping to "step up my game" a bit in terms of designing it for the next wave of videos, and seeing your setup gave me an improvement idea or two!
