This video lesson introduces the fundamental concepts and variables used to describe rotational motion of rigid bodies. It draws parallels with linear motion to simplify understanding of angular position, displacement, velocity, and...

Ever wonder why toast often lands butter-side down? This video explains the rotational motion of a falling object in free fall and calculates the angular speeds required for butter-side down landings

What is the difference between linear velocity and angular velocity? In this video we will derive the formula for linear velocity (or speed) and angular velocity. Then, we will use those formulas and compare and contrast the two rates.

Curious about rotational kinematics? In this video, we break down key concepts like angular displacement, velocity, and acceleration, using simple demonstrations. Perfect for AP Physics 1 students or anyone looking to understand...

In 1913, Niels Bohr proposed an atomic model that dramatically altered our comprehension of atomic structure by establishing a novel framework for describing the arrangement and behaviour of electrons within an atom....

The tangential velocity is measured at any point tangent to a rotating wheel. Thus, angular velocity, w, is related to tangential velocity, Vt, through the formula: Vt = wr. Here, r is the radius of the wheel. Tangential velocity is the...

In this episode, we focus on the change in magnetic flux and the emergence of back electromotive force (emf). Follow along as we dissect the side view of a current-carrying wire loop rotating in a magnetic field. Unravel the concept of...

This video will explain and illustrate how to describe and measure rotational motion.

Back EMF Demonstration

This problem is about the average power input to a wheel when we know the moment of inertia of the wheel, the change in angular velocity and the time interval.

This problem is about the average net torque on a wheel when we know the change in its angular speed, moment of inertia and change in time.

This problem is about determining the magnitude of the centripetal acceleration of an object moving in a circle, however, you might not initially identify it as such.

This problem is about what happens to angular speed, tangential acceleration and centripetal acceleration for a satellite in a circular orbit.

This problem is about the relationship between frequency and radius for a charged particle moving in a circle in a constant magnetic field.

This is a review of all of the dimensions used in AP Physics C - Mechanics. Okay, maybe it doesn't cover some of the basic dimensions, however, if you don't know that linear velocity is in furlongs per fortnight, then I probably can't...
