Introductory Rotational Form of Newton's Second Law Problem

The video tutorial explains how to calculate the angular acceleration of a uniform solid disk. It begins with a problem statement involving a disk, a string, and a force. The rotational inertia is calculated, followed by a free body diagram to identify forces and torques. The angular acceleration is then determined using the relationship between torque and rotational inertia. The tutorial concludes with a discussion on the choice of direction for torque and angular acceleration, emphasizing the importance of consistent definitions in physics problems.
