In a closed physical system, the sum of all angular momentum remains constant -- says an important physical law of conservation. Angular momentum does not necessarily need to involve "real" bodily ...

For all other positions of P, there is a more complicated relationship between R and the speed of P. We need to look at both the conservation of energy and conservation of angular momentum in order to ...

To compensate and keep angular momentum constant, the washer's angular velocity has to increase. The reverse happens when you loosen the string and allow the washer to move out farther.

Speedy Spinning Spheres! Using spheres, cylinders, and straws, the Crew and Dr. Rob learn about inertia, velocity, and conservation of energy due to angular momentum. STEM Challenge: Angular ...

The angular momentum can be in a different direction than the angular velocity - but in this case, I is not a scalar quantity. Here is the short scoop on the angular momentum principle.
