# AP Physics C (Delve Class)

AP Physics C is taught over approximately thirty classes over the entire school year, for Delve 2011-2012

## Homework Assignments

All assignments are given from Giancoli's Physics, except where otherwise given. Level I problems are drill problems that just test the ability to regurgitate information learned. Level II test problem solving skills on some basic level. Level III problems are generally chosen to be fun, and are usually hard. Finally, the suggested readings are usually sections of the book that contain some interesting information.

• Class of 3/01/12

Quiz on capacitors, inductors, and circuits containing them. The quiz is online.

• Capacitance. More discussion of RC, RL, LC circuits. Problems were slow this week, again, because both Pavel and Jeffrey were very busy. Sorry!

• Capacitance and capacitors. Dielectrics and diamagnetics. Inductors. Derived the transient equations for RC and RL circuits, and also analyzed steady-state behavior. Sorry for how late these problems came out; Pavel and Jeffrey were very busy coming up on Spring break.

• Class of 2/04/12

Quiz on magnetic fields and Faraday's and Ampere's laws. The quiz is online.

• More problems on Faraday's Law of induction. A problem discussed is that of a loop of wire in the magnetic field of a wire; see the live demo/simulation of this problem.

• Faraday's Law of electromagnetic induction. Generators, metal detectors, transformers, and ground fault circuit interrupters.

• More currents, wires, and magnetic fields. A long derivation with the Biot-Savart law and a discussion of various applications of magnetic fields.

• Current, wires, and magnetic fields. Ampere's law for finding the magnetic field in nice circumstances. Finally, a brief discussion of the duality of electric and magnetic fields due to special relativity, and how the world of a photon looks.

• Class of 1/29/12

Quiz on electric fields and potentials, Gauss's Law, and basic circuits. The quiz is online.

• Circuits and solving circuits with resistors.

• Class of 1/15/12

Cumulative quiz on all of mechanics. If you lost yours or did not manage to be present, a copy is online.

• Quick multi-variable calculus introduction (volume, surface, and path integrals). Gauss's Law. Electric field of a plane of charge.

• Beginning of electricity and magnetism. Charge and Coulomb's law, and charge distributions. Electric field and electric potential.

• Class of 12/11/11

Quiz on energy and statics. If you lost yours, a copy of the quiz itself is online.

• Rotational kinetic energy and problem session on energy.

• Class of 11/27/11

Energy: potential and kinetic. Gravitational potential energy and Kepler's laws.

• Class of 11/20/11

No class due to ESP Splash running.

• Problem Set 6 (Given 11/13/11)

Statics and balance. On braking bikes and poorly-constructed hotels.

Level I
Problem 9.2, 9.7, 9.13, 9.14, 9.17, 9.36, 9.57, 9.59, 9.63
Level II
Problem 9.25, 9.27, 9.29, 9.37, 9.62, 9.71, 9.67, 9.73
Level III

Suggested Reading: Section 9-7, "Spanning a Space: Arches and Domes", in your textbook.

• Class of 11/6/11

Quiz on kinematics, force, and momentum. If you're interested in looking it over and have lost your copy, both the multiple choice and free response portions are available.

• Class of 10/30/11

Class canceled due to snow fall. I know, crazy!

• Class of 10/23/11

A Spicy Delve day. Momentum problems. Angular vs linear momentum.

Next class is a quiz day, so no homework to let y'all study.

• Problem Set 5 (Given 10/16/11)

Momentum and collisions. Angular momentum. How to punch properly.

Our apologies for how long it took to put this up; there have been difficulties getting a textbook to get problems out of.

Level I
