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 ...

In physics when something stays the same we say it is conserved. ... so her angular velocity has to increase in order to keep her angular momentum constant.

For the angular velocity, ... He enjoys teaching and talking about physics. Sometimes he takes things apart and can't put them back together. ...

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 ...

The measured angular acceleration was 1.6 million degrees per second squared – which is about three times greater than the acceleration of the arm of a professional baseball pitcher. A pitcher, ...
