THIS WEEK’S CALENDAR � Monday � Web. Assign should be operational for all � i-clicker now in use. � Complete discussion of Unit 01 � Begin Unit 02 – A different type of unit. Wednesday � Hope to finish most of Coulomb’s Law � First Web. Assign will go postal � Download & Print Unit 03 Friday � First Quiz � Some problems � Possible work on Electric Field Unit � � � You can’t get points without your clickers.

NEW UNIT – COULOMBS LAW � More on how charge behaves in the presence of other charges. � We will indirectly DEFINE charge and its SI units. � We will see that the force between two charges is given by Coulomb’s Law � REMEMBER � The that force is a VECTOR!!! problems are mostly solved like free-body diagrams from last semester. � First Web. Assign will pop up tomorrow.

NOTES: � Link to Shoot the monkey does not work. If you wish, you can find it from home by searching Google for: “shoot the monkey”, applet � There a number of problems at the end of the Unit. Since the equivalent to these will appear on Web. Assign (look!), you do not have to complete all of them in class. If we have time we will discuss some of the solutions. GET TO WORK!
