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.

Review Blast: Projectiles (Levels: Intro, APB, APC)

This podcast is a very quick review of projectile ideas, including the differences between x- and y- components of motion, how to solve problems when projectiles are launched horizontally, and what additional thinking is involved if a projectile is launched at an initial angle.

Intro to Vector Addition (Levels: Intro, APB, APC)

This podcast introduces you to how to add vectors graphically, and also how to use basic trig to solve for resultants and vector components. (Only deals with parallel and perpendicular pairs of vectors.)

Displacement, Velocity, & Acceleration Concepts (Levels: Intro, APB, APC)

This podcast introduces concepts of displacement, velocity, and acceleration. Basic calculations are discussed, as well as the meanings of positive and negative values for those three quantities in straight-line motion situations.
