Chapter 11

Chapter 11. Angular Momentum. Angular Momentum. Angular momentum plays a key role in rotational dynamics. There is a principle of conservation of angular momentum. In analogy to the principle of conservation of linear momentum The angular momentum of an isolated system is constant.

Chapter 11. Angular Momentum. The Vector Product. There are instances where the product of two vectors is another vector Earlier we saw where the product of two vectors was a scalar This was called the dot product The vector product of two vectors is also called the cross product.

Chapter 11

Chapter 11. Angular Momentum. The Vector Product and Torque. The torque vector lies in a direction perpendicular to the plane formed by the position vector and the force vector The torque is the vector (or cross) product of the position vector and the force vector. Torque Vector Example.

Angular Momentum

Angular Momentum. Inertia and Velocity. In the law of action we began with mass and acceleration F = ma This was generalized to use momentum: p = mv. Moment of Momentum. To continue the analysis of rotational motion, we must also extend the idea of momentum. p. r. Law of Angular Inertia.
