Assignment 8 (Oct 9)
 

 Keep ahead. 

Circular motion/Friction/ Work/Energy/ Momentum(inelastic one dim) /Gravitation (two sections)....

Keep up on the online quizzes.  

 Some notes on momentum....we will stick to mostly perfectly inelastic collisions (where objects stick together).  Some discussion of elastic and two dimensional collisions...but not much more than discuss. 

In class quiz tomorrow on Oct. 10.  Be able to calculate a number for work given information on the motion of an object (definition).  Be able to calculate KE for similar info given.  What happens to KE of an object when the speed doubles---IT DOES NOT DOUBLE.
