Khan Academy: Radius Comparison From Velocity and 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...

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]

A video exploring how angular velocity relates to speed. [9:24]

Video tutorial shows how to determine how fast something will be traveling upon impact when it is released from a given height. [11:42]

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]

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 when there is no net torque. [5:55]

Explaining group and period trends in atomic and ionic radii. [11:26]

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 tutorial uses examples and formulas to show how to derive displacement as a function of time, constant acceleration, and initial velocity. [9:57]
