Derivation of Pendulum equations method 4

The video tutorial explains how to calculate the equations of motion for a pendulum using the sum of torques and moment of inertia. It begins with an introduction to the method, followed by creating a free body diagram to analyze forces. The tutorial then covers torque calculation, moment of inertia, and concludes with deriving the final equation for pendulum motion.

What is the relationship between the torque and the angular acceleration in the context of the pendulum?

What does the negative sign in the equation for angular acceleration indicate about the direction of motion?

How is the moment of inertia calculated for the pendulum system described?
