Lecture
This lecture covers the concepts of momentum, impulse, and center of mass in physics, discussing scenarios like the conservation of momentum in elastic collisions, the impact of different surfaces on objects, and the calculation of the center of mass in complex systems. Examples include skydiving scenarios with drag coefficients and terminal velocities, as well as the determination of wind speed for indoor skydiving. The lecture also addresses conceptual questions related to these topics, providing a comprehensive understanding of fundamental principles in mechanics.
