Energy in Simple Harmonic Motion (Levels: APB, APC)

This podcast explains how to think about the energy of a simple harmonic oscillator (specifically a mass-spring system), and also how to solve related problems.

Review Blast: Forces during Rolling (Level: APC)

This podcast is a very quick review of what forces are acting on a rolling object, and how those forces affect the object's motion.

Review Blast: Rotational Energy Conservation (Level: APC)

This podcast is a very quick review of how to use energy-conservation ideas when an object is rotating during its motion.

Center of Mass (APC)

This podcast introduces the concept of center of mass, both for a system of particles and for irregularly-shaped objects.

Review Blast: Energy Conservation (Levels: Intro, APB, APC)

This podcast is a very quick review of how to use energy-conservation ideas to solve motion problems where no friction is involved, and also what extra thinking to use when friction is involved.

Work, Energy, & Momentum Conceptual Questions (Intro, APB, APC)

This podcast is intended to review some conceptual ideas related to work, energy, and momentum. It just consists of 8 conceptual questions, with answers discussed.

Potential Energy Curves (APC)

This podcast introduces Potential Energy Curves, after students are already familiar with energy concepts such as kinetic and potential energies, and also E-conservation.
