Alternate Uniformly Accelerated Motion (UAM) equations are introduced. The derivative is used to derive one UAM equations from another UAM equation.

Standing longitudinal waves are demonstrated and compared to an animation to help with understanding what the heck is going on.

The equations for the harmonic frequencies of open and closed pipe wind instruments are derived. An animation of a longitudinal standing wave pattern in a closed pipe is shown. Displacement and pressure nodes and antinodes are shown.

When standing waves are allowed at 15, 30, and 45 hertz on a string, then we should not see a standing wave pattern at 22 hertz. Yet, we do in this demonstration. This explains why.

Reflection with and without inversion caused by fixed and free ends are demonstrated. Standing wave patterns at 5 different frequencies are demonstrated. A standing wave animation is shown to understand to how standing wave patterns are...

Cartesian and polar coordinates are introduced and how to switch from one to the other is derived. The concept of angular displacement and arc length are demonstrated. Circumference is shown to be an arc length.

What is the angular acceleration of a compact disc that turns through 3.25 revolutions while it uniformly slows to a stop in 2.27 seconds?
