PPT-Angular Momentum

What was Angular Momentum Again If a particle is confined to going around a sphere At any instant the particle is on a particular circle r v The particle is some distance from the origin r. 186 dt The angular momentum of the particle is conserved, if the torque = Stepan. .

An observed relation between the most basic morphological classification and a fundamental physical quantity: the specific angular momentum (. Momentum Defined. p. = m . v. p. = momentum vector. m. = mass. v. = velocity vector. Momentum Facts. Linear Momentum. p. = m . v. Momentum is a vector quantity!. Velocity and momentum vectors point in the same direction.. Physics 1, NTC. Angular Motion, General Notes. When a rigid object rotates about a fixed axis in a given time interval, every portion on the object rotates through the same angle in a given time interval and has the same angular speed and the same angular acceleration..

Identify that smooth rolling can be considered as a combination of pure translation and pure rotation.. Movement around a fixed point or axis. Spin; somersault . Occurs when a force is applied outside the centre of mass. An off centre force is referred to as an eccentric force.. Examples of a force being applied outside the centre of mass of an object or body to cause rotation. . AP Physics. Work-Energy Theorem for Rotation.  .  .  .  . End Slide.  .  .  . Work-Energy Theorem for Rotation.  .  . End Slide.  .  .  .  .  .  .  .  .  . Work-Energy Theorem for 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 . 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.
