Khan Academy: Relationship Between Angular Velocity and Speed

This video lecture explains how angular velocity relates to speed. Video discusses how angular velocity is the change in angle over a change in time. [9:24]

Learn about the relationship between Ka of a weak acid and Kb for its conjugate base. Practice equations for converting between Ka and Kb, and converting between pKa and pKb.

Learn about the relationship between Ka and Kb, and pKa and pKb. See examples of finding Ka of a weak acid given Kb of the conjugate base. [11:20]

The video lesson from Khan Academy provides a lesson for the AP Chemistry course. This video lesson explains the relationship between Ka and Kb, and pKa and pKb. Examples of finding Ka of a weak acid given Kb of the conjugate base.

A video discussing uniform circular motion, Learn how in uniform circular motion, angular velocity is a vector quantity and is equal to the angular displacement divided by the change in time. [7:30]

In the following interactive module, students will begin to explain the relationships between instantaneous velocity, average velocity, instantaneous speed, average speed, displacement, and time. They will calculate velocity and speed...

Watch as Sal Khan predicts which spinning disc has a larger radius from angular velocity and the linear velocity of a point on the edge. [3:58]

Do curves slow runners down or help their speed? Pupils simulate a 200-meter dash to calculate the angular and linear velocity of a runner. They then determine whether the runner is faster around the curved section of the track...

This video teaches the viewer how to read a position vs. time graph. It explains how to use the graph to determine the following quantities: displacement, distance, average velocity, average speed, instantaneous velocity, and...
