Law Of Conservation Of Angular Momentum

原声例句
Vox 观点

It seems to be able to right itself by flipping in the air without pushing off anything first, which would contradict the law of conservation of angular momentum.

它似乎能够通过在空中翻转而不首先推动任何东西来调整自己，这与角动量守恒定律相矛盾。

Angular momentum

This gyroscope remains upright while spinning due to the conservation of its angular momentum.
Velocity of the particle m with respect to the origin O can be resolved into components parallel to (v//) and perpendicular to (v⊥) the radius vector r. The angular momentum of m is proportional to the perpendicular component v⊥ of the velocity, or equivalently, to the perpendicular distance r⊥ from the origin.
Moment of inertia (shown here), and therefore angular momentum, is different for every possible configuration of mass and axis of rotation.

In physics, angular momentum (rarely, moment of momentum or rotational momentum) is the rotational analog of linear momentum. It is an important quantity in physics because it is a conserved quantity – the angular momentum of a system remains constant unless acted on by an external torque.
