Identify that smooth rolling can be considered as a combination of pure translation and pure rotation.. Purpose/Problem. Conservation of . angular momentum.  is the principle that the angular momentum of an object remains constant as long as no external . torque,.  or moment, acts on that object. When a figure skater is in the air, he or she is rotating about his or her center of mass and possess a certain amount of angular momentum. The only external force is gravity. However, gravity acts vertically down through the . Students:. Ashraf . Jodeh. Ameer . Hasan. Bashar . Alqerm. Yousof. . Odeh. Contents. Abstract. What is Gyroscope ?. History. Problem Definition. Gyroscopic Principles. Manufacturing (Mechanical and Electrical parts). Momentum and Impulse. Objectives:. 1. Compare the momentum of different moving objects.. 2. Compare the momentum of the same object moving with different velocities.. 3. Identify some examples of change in the momentum of an object.. Rotational Motion – Torque and Angular Momentum AP Physics 1 Torque Forces with equal strength will have different effects on a swinging door. The ability of a force to cause rotation depends Michael Fowler, UVa . Torque as a Vector. Suppose we have a wheel spinning about a fixed axis: then always points along the axis—so points along the axis too.. If we want to write a vector equation. L. B. >L. A. =L. F. =L. G. >L. E. >L.
