Free-Body Diagrams

043 - Free-Body Diagrams

In this video Paul Andersen explains how free-body diagrams can be used to solve kinematics problems. The only two parts of a free-body diagram are the object and all external forces acting on the object. Numerous situations are presented and free-body diagrams for each are illustrated.

I thought that this video was too short. I wish the explanations had been a little more thorough and terms defined. And, I am a great fan.

Anyone plz. 4:05 How is friction exerted by the ground on the car is to the left when the car is actually accelerating to the right.

[PIANOSTYLE]

revisiting statics trying to get well grounded. once I get to that point the math will be just plugging in. I've noticed unless I know a subject thoroughly I get side tracked. looking forward to viewing your videos.

What exactly is the difference between these two "Forces exerted by the body" and "the body"?
