Open Stax: Rotation Angle and Angular Velocity

Explanations for six different physics lab activities and five suggested assessments are contained in this resource by the National Science Teachers Association. Any combination can be used to open learners' eyes to rotational motion....

Don't let rotational motion make your head spin—use a video lesson to highlight the important ideas related to this concept! The 11th lesson in a physics series breaks down the motion in a rotating object. The narrator includes a...

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

Learners establish the angular velocity of the Sun and determine how long it takes the Sun to make one complete revolution. They determine what angular velocity is and how it can be useful in determining the speed and direction of any...

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]

Sal Khan explains linear velocity from the radius and angular velocity using two pumpkin catapults with different arm lengths as an example. [5:30]

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]

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]

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...

A double pendulum model where the angles and angular velocities can be manipulated and the effects observed.
