## U7 Static Electricity

This unit looks at the energy and forces between charges

At the end of the unit you should be able to:

Student Formula Sheet blank graph paper

Worksheet #1 Coulomb's Law and Electric Field Worksheet #1 solutions

Worksheet #2 Force, Electric Field, Potential Energy, Voltage Worksheet #2 solutions

Worksheet #3 more complex problems Worksheet #3 solutions

Your job is to spend one period learning about a topic related to static electricity.

Possible questions to start with include . . .

Is it safe to have a bath when there is lightning outside? Quirks

How are fires started and prevented by static electricity at gas stations? Globe and Mail

Why aren't people in air planes hurt when the plane is struck by lightening? Sci Am

You can also pick your own question.

Product can be this template or an appropriate option that you run by me.

At the end of the unit you should be able to:

- calculate the force between two charges at a set distance
- calculate the electric field at a point in space from one or more charges
- calculate how much energy it takes to place two charges close to each other
- calculate the voltage or electric potential at any point in space due to one or more charges
