Net Torque & Rotational Kinematics

Net Torque

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.
