3. Spinning toy tops http://www.youtube.com/watch?v=LDXAhwhsZ9k If the top were not spinning, what would happen to it?

4. Rotational Motion in Diving

5. Right Hand Rule for Angular Velocity

6. Rigid Body Rotation

7. Iclicker Question #1 Consider a CD disk spinning around about its geometric center. Which of the following statements is true concerning a point on the inner track of the CD compared to a point on the outer track of the CD? • Both the inner track and the outer track have the same angular velocity. • Both tracks have the same tangential acceleration. • Both tracks have the same velocity. • The tracks have different centripetal accelerations • I can not tell because the stupid CD is scratched.

8. Rotational Kinetic Energy

9. Iclicker Question #2 Which should have a larger moment of inertia, a ring of material with radius R and total mass M or a solid disk of mass R and same total mass M? • The ring • The solid disk • Both should have the same moment of inertia • It depends upon the material used to make the ring • “One Ring to rule them all, One Ring to find them,One Ring to bring them all and in the darkness bind them..”
