The equation is valid only if \sum \tau and \bar L are measured about the same origin. Furthermore, the expression is valid for any origin fixed in an inertia frame. 也就是说,当没有torque的时候, d\bar L/dt=0, angular momentum为常量。 Angular momentum of a system of particles The ...
Angular momentum definition: the product of the moment of inertia of a body about an axis and its angular velocity with respect to the same axis.. See examples of ANGULAR MOMENTUM used in a sentence.
momentum about an axis through the center of its path = L r p Ex. 11.3: Angular Momentum of a Particle in Circular Motion • Angular Momentum of a System of Particles = vector sum of the angular momenta of the each particle: • Differentiating with respect to time gives Newton’s...

The resultant torque acting on an object about an axis through the center of mass equals the time of change of angular momentum regardless of the motion of the center of mass. This theorem applies even if the center of mass is accelerating,provided and are evaluated relative to the center of...

The larger is the angular momentum L, the smaller is the angle θ, the less successful a given torque will be in changing the direction of the axis of the spinning object. The spinning motion is more stability. Therefore the direction of the axis of rotation is changed by an angle...
