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.

Velocity-Time Graphs (Levels: Intro, APB, APC)

This podcast discusses how to represent different motions on velocity-time graphs, including the meaning of slope and area these graphs.

Position-Time Graphs (Levels: Intro, APB, APC)

This podcast discusses how different motions are represented on graphs of position versus time, with a special emphasis on the meaning of slope for these graphs.
