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 ...

Instead of velocity we say, “angular velocity,” which measures how fast an object rotates. Finally, instead of momentum, we say “angular momentum.” Even though the terms are a little ...

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.
