1. Coulomb’s law and the electric field
Charge and Beyond– Week 2/1
Coulomb’s law and the electric field

2. NOTE:
these short presentations will usually be posted on the class website, normally without the clicker questions.

3. evil clicker numbers

#F  missing a digit???

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

5. charge
insulators
conductors
semiconductors

7. Charging Diagrams – (induction)

8. bad hair
INSULATOR IS POLARIZED

9. 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 that force is a VECTOR!!!
The problems are mostly solved like free-body diagrams from last semester.
First WebAssign will pop up tomorrow.

10. 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 are a number of problems at the end of the Unit. Since the equivalent to these will appear on WebAssign (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!
