Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

At t 2, the angular velocity is zero, with a non-zero (positive) angular acceleration. At that time, the direction of rotation for BC is changing from CW to CCW. In summary, you should never assume ...

Angular momentum is an object's moment of inertia times its angular velocity. If one of the latter two increases, the other decreases, and vice versa.

Shown in right video is the TOTAL angular velocity vector (MAGENTA) of the rotor, which is the vector sum of the red and blue angular velocity components. Note that the magnitude of the total angular ...

Stretching the limbs out will increase the moment of inertia, therefore decreasing the angular velocity — which is essential for a neat and flawless dive into the water. Phase 2.

Now for angular momentum. The angular momentum is a quantity that we can calculate for rotating object. It's the product of the angular velocity (how fast it spins—represented with the symbol ω ...

The empty bottle’s angular velocity, therefore, stays the same as it flies through the air just like a spinning coin. That makes it very hard to control the bottle's descent and difficult to get ...

At the first position, the person has an angular velocity and moment of inertia of: Quick note: the "2" subscript is there because this is after the person jumped off the merry go round.
