In this video I introduce the concept of net torque and we do some quick net torque calculations for various word problems and situations.
Net Torque T=Iα Kinematic Problems
In these problems we analyze the angular acceleration and velocity of objects when they are subjected to a force. In the last one we bring kinematics to the party by calculating the spin on a tennis ball after it is struck and spun by a racket.
If you do not have an account, you should get one, because it is awesome! You can save a playlist for each test or each chapter, and save your "greatest hits" into a "watch right before the final" list (not that we recommend cramming, but when in Rome...)
