Angular Momentum and Torque: Exploring Rotational Dynamics and Conservation Principles
This PowerPoint explores angular momentum, torque, and their applications in rotational dynamics. It defines angular momentum as the cross product of position vector and momentum (L = r × p) and discusses the rate of change of angular momentum due to torque. The presentation also highlights key concepts such as Kepler’s second law, where a planet sweeps equal areas in equal times, and the angular momentum is conserved. Examples like a person walking on a turntable and a yo-yo are used to illustrate the conservation of angular momentum. Additionally, it discusses the relationship between angular velocity and angular momentum, emphasizing the parallelism in certain symmetric rotational motions.
