Introduction:
If you haven't gotten really charged up over physics yet, here's your chance. Electrostatics
studies how charged particles interact with each other and those things which will influence their
behavior. Essentially we are studying what happens when something either has too many or too
few electrons. You experience one result of this nature whenever you shock yourself after
walking across a carpeted floor and touching a metal doorknob. The question we ask here is what
happened as you shocked yourself and why did it occur in any case? |

Insulator |
| Electric Potential Energy |
Charge by Induction |
Charge by Conduction |
Electroscope |
| Electrophorus |
Ground |
Point Charge |

Superposition |
|
2) Differentiate among point charges and charge distributions.
|
|
3) Explain the difference between electric potential and electric potential energy.
|
|
4) Calculate the electric field at a point in space from multiple charges.
|
|
5) Determine the force on a charge from other particles and between parallel plates.
|
|
6) Distinguish between charging by induction versus charging by conduction.
|
7) Use electric potential energy in concert with conservation of energy to determine the speed
of a charged particle.
