This video tutorial covers key concepts in AP Physics 1, focusing on torque and rotational motion. It begins with angular kinematics, explaining angular position, velocity, and acceleration, and their relationship with linear motion. The tutorial then delves into rotational torque, discussing how it causes angular acceleration and the role of moment of inertia. Rotational energy is explored, highlighting the conversion between potential and kinetic energy during motion. Finally, angular momentum is examined, emphasizing its conservation in collisions and its relation to torque.
