Khan Academy: Linear Velocity Comparison From Radius & Angular Velocity: Example

Physics fanatics time five cars as they pass on the highway. They use the times and a 20-yard distance to calculate velocity. They also graph distance vs. time. A page of student pre-lab questions is provided in addition to the activity...

Watch this tutorial about distance, displacement, speed and velocity. Find out the difference between vectors and scalars. [8:38]

Practice comparing the boiling point of nonane and 2,3,4-trifluoropentane. A sample multiple choice problem from the 2014 AP Chem course description. [6:19]

Sal Khan explains how to derive the formula for centripetal acceleration in terms of angular velocity using linear speed formula. [5:29]

Drawing shell models to explain the Bohr Model Radii and determine the velocity of the ground state electron. [6:57]

An explanation that uses physics to derive the Bohr model radii. [10:52]

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...

Video explores the difference between vectors and scalars while discussing distance, displacement, speed and velocity. [8:38]

A video exploring angular momentum which is how much movement an object has when it's rotating in a circle. Look at how the equation for angular momentum is derived. [11:18]
