UNIT 6  ANGULAR MOMENTUM

a) Students should be able to use the vector product and the righthand rule, so they can: 
 (1) Calculate the torque of a specified force about an arbitrary origin.
 (2) Calculate the angular momentum vector for a moving particle.
 (3) Calculate the angular momentum vector for a rotating rigid object in simple cases where this vector lies parallel to the angular velocity vector.

b) Students should understand angular momentum conservation, so they can: 
 (1) Recognize the conditions under which the law of conservation is applicable and relate this law to one and twoparticle systems such as satellite orbits.
 (2) State the relation between net external torque and angular momentum, and identify situations in which angular momentum is conserved.
 (3) Analyze problems in which the moment of inertia of an object is changed as it rotates freely about a fixed axis.
 (4) Analyze a collision between a moving particle and a rigid object that can rotate about a fixed axis or about its center of mass.
