Forces During Rolling (Level: APC)

This podcast explains how to examine forces and torques while an object is rolling.

Torque & Newton's 2nd Law for Rotation (Level: APC)

This podcast explains what torque is, and how to calculate it.  Newton's 2nd Law is also revisited, from a rotational perspective.

Review Blast: Gauss' Law (Level: APC)

This podcast is a quick review of Gauss' Law, including conductors in electrostatic equilibrium, E-field due to spherical conductors & non-conductors, E-field due to sheets of charge, and E-field due to lines of charge.

Thermal Conduction Problems (Level: APB)

This podcast introduces the formula for calculating rate of heat transfer through conduction, with an example problem to help demonstrate how the formula is used.

Heat as Energy Transfer (Level: APB)

This podcast explains the definition of heat, and how it differs from internal energy. It also explains conduction, convection, and radiation as the three methods of heat transfer.

Thermal Expansion (Level: APB)

This podcast discusses calculations for the linear and volume expansion of objects when heated.

SHM & Uniform Circular Motion (Level: APC)

This podcast deals with the similarities between simple harmonic motion and uniform circular motion. Problem-solving is discussed, using functions for position, velocity, and acceleration of a simple harmonic oscillator.
