Presentation Transcript

  1. Rotational Energy and Angular Momentum

  2. Rotational Energy Translational Rotational

  3. Example What are the translational and rotational kinetic energies of a wheel that is rolling at 10 m/s, has a radius of 0.3 m, a mass of 2 kg and a moment of inertia of 0.09 kgm2?

  4. Angular Momentum Angular momentum is conserved if there is no net outside torque.

  5. Example http://www.sparknotes.com/testprep/books/sat2/physics/chapter10section6.rhtml

  6. A skater is spinning with an angular speed of 4 rad/s with his arms extended. By pulling his arms in, he reduces his moment of inertia from 10 kgm2 to 5 kgm2. What is his new angular speed? Before After
