The video tutorial introduces torque, explaining its relation to the center of mass and how force applied away from the center causes rotation. Torque is defined as the product of force and distance, with units of newton meters. The video differentiates torque from work, emphasizing that torque involves perpendicular force and distance vectors. An example calculation demonstrates how to determine torque and discusses the concept of balancing torques, highlighting mechanical advantage.
