2024年2月14日 · But you have constrained the problem by confining the particle to a ring in the ##xy## plane. That means the problem is no longer three dimensional and what you are calling "the x,y components of angular momentum" are no longer even physically meaningful, since you have made it physically impossible for anything to rotate except in the ##xy ...

2012年4月28日 · It is explained that the angular momentum is not just mvr, but also includes the angle between r and v. The conversation also touches on the relationship between angular momentum and rotation, and how it can be derived using symmetries. Additionally, it is noted that the value of angular momentum depends on the origin of the coordinate system.

2019年1月30日 · (a) Is the angular momentum of the ball conserved? No, the angular momentum ##L = mvl##, where m is the mass of the ball and v is its speed at an instant. Note, this is an example of (non-uniform) circular motion whereby vector v …

2015年6月29日 · Orbital angular momentum is a kinetical quantity of a moving body, it can always be related to the change of spatial degree of freedom. EDIT: I didn't pay a close attention to your question, I thought you wrote orbital angular momentum. So, spin is an angular momentum, just orbital angular momentum is.

2020年10月25日 · "The angular momentum of an isolated system remains constant in both magnitude and direction. The angular momentum is defined as the product of the moment of inertia I and the angular velocity. The angular momentum is a vector quantity and the vector sum of the angular momenta of the parts of an isolated system is constant.

2009年3月9日 · Angular Angular momentum Momentum Symbol In summary, the angular momentum symbol, "L," is based on the right hand rule of vector cross products. It represents the radius of a circle drawn around a point that has the same translational momentum as the object.

2019年12月4日 · Both linear and angular momentum are conserved. Equations are equations and if they include common variables they can be combined in any way that is mathematically valid. PS remember that angular momentum is defined relative to a given point. So, you are also free to choose the point about which you measure angular momentum of the system.

Determine the angular momentum of the Earth a) about its axis of rotation (assume the Earth is a uniform sphere), and b) in its orbit around the Sun (treat the Earth as a particle in a circular orbit around the Sun). The Earth has a mass of 6.0×1024 kg and a radius of 6.4×106 m; it is 1.5×108 km from the Sun.

2011年5月20日 · In summary, conservation of angular momentum is satisfied by the pendulum's vertical direction due to the lack of external torque. The fluctuations in angular momentum of the pendulum are matched by opposite fluctuations in the angular momentum of the Earth, as both external forces come from the Earth.
