Intro to RC Circuits (APC)

This podcast introduces concepts related to RC circuits - circuits with a resistor and capacitor in series with a voltage source. Intended to intro the ideas to students who have already learned capacitor ideas and are in the midst of studying electric circuits.

Magnetic Directions Review (APB, APC)

This podcast reviews rules for determining directions in magnetic field problems. Topics include the right-hand rule for forces on currents and charges, right-hand rule for B-field created by a current, and Lenz's law.

Electric Force Problems (Levels: Intro, APB, APC)

This podcast is a review of how to use vector addition ideas, along with Coulomb's law, to find the net force acting on a charge when it is pushed/pulled by multiple electric forces.

2nd Law Problems with Connected Objects (Levels: Intro, APB, APC)

This podcast describes strategies for solving problems involving connected objects, through working two examples of this type of problem.

2nd Law Problems with Multiple Forces (Levels: Intro, APB, APC)

This podcast provides extra practice with 'easy' one-dimensional equilibrium problems, and also with problems using Newton's 2nd Law when multiple forces are involved.

Basic Derivatives in Physics (Level: APC)

This podcast for AP Physics C students reviews how to use the power rule and product rule to perform derivatives, and then how to apply derivatives to find velocity and acceleration functions.

Motional emf (APB)

This podcast introduces the concept of motional emf, relating it to Faraday's law of induction.
