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.

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.
