For New Units

Seniors, periods 1-2, 5-6, 8-9:

We will be starting capacitors and how these behave in circuits. Turns out plain capacitor circuits will hopefully look a lot like resistor circuits, as far as how we analyze them. We will still have Kirchhoff's rules. Ohm's law for capacitors will be Q = CV, since this is what capacitors do - they store charge in circuits.

Watch and take detailed notes on two videos.
Take a look at a video for finding total capacitance in series and parallel. The new unit that measures capacitance is called a farad, F, after Michael Faraday.
Then, check out a video on how to find stored charge on capacitors (this is like finding currents flowing through resistors). Note that capacitors in series have the same charge, and in parallel the same voltage.


Period 3:
We are starting momentum. This is a word you have all heard, but now we will be defining it and using it to help us understand collisions of all types.

Watch and take notes on two videos. One is an introduction to momentum.  The second is defining what impulse, or a change in momentum, is for objects when there is a collision.
