Physics 6010, Fall 2010 Symmetries and Conservation Laws
... Rotational Symmetry and Conservation of Angular Momentum Here we demonstrate that rotational symmetry of a Lagrangian leads to conservation of angular momentum. You have already seen an example of this: the particle moving in a central force has the spherical coordinate φ as a cyclic variable. The c ...

... Conservation of Angular Momentum, cont If the system is deformable such that the mass of the isolated system undergoes redistribution, the moment of inertia changes. The conservation of angular momentum requires a compensating change in the angular velocity. Ii wi = If wf = constant This hold ...

... Conservation of Momentum applies only in the absence of external forces! In the first two sample problems, we dealt with a frictionless surface. We couldn’t simply conserve momentum if friction had been present because, as the proof on the last slide shows, there would be another force (friction) i ...

... D E = D K + D U = -fkd if friction forces are doing work on the system. The total amount of energy in the system is still constant, but the change in mechanical energy goes into “internal energy” or heat. ...

Ch12 Motion Notes and Practice problems with explanations
... Fortunately, the way that we use the word momentum in everyday life is consistent with the definition of momentum in physics. For example, we say that a BMW driving 20 miles per hour has less momentum than the same car speeding on the highway at 80 miles per hour. Additionally, we know that if a lar ...
