Unit 11 Problem 4 - Rotational Dynamics - A Falling Rod Rotating About One End

If we pin one end of a rod and then let it fall, we'll arrive at the interesting result that the end of the rod will fall faster than a free-falling object.

V= “sq root” (3gL)

[@TadThurston]

Yes! Thanks for catching it.

[@sachinrath219]

why the work done by torque not considered potential energy mgh is not a part of rotational dynamics, thanks
