Angular Angular momentum Conservation Momentum

In summary, the conversation discusses the issue of conservation of energy and momentum in a tetherball system. It is argued that while the angular momentum of the universe as a whole is conserved, the angular momentum of individual systems, such as a tetherball, may not be conserved due to external forces and torques. This concept is further discussed in a thread on the topic, where it is shown that the kinetic energy of the ball should be conserved, but the angular momentum around the pole is not. However, in a larger system including the pole and Earth, angular momentum is conserved. The conversation also brings up the example of

You still have not shown ANY understanding of the fact that the tetherball in your example undergoes coupling with an external source.

If you still think you have found a violation of angular momentum, you are welcome to submit to the IR section. This thread has gone nowhere but round and round and round like the tetherball. It is now done.

1. What is the conservation of angular momentum?

The conservation of angular momentum is a fundamental law in physics that states that the total angular momentum of a system remains constant in the absence of external torques.

2. How is angular momentum conserved?

Angular momentum is conserved because of the principle of action and reaction. When a force is applied to an object, an equal and opposite force is also applied to the object in the opposite direction, resulting in no change in the total angular momentum of the system.

3. What happens when there is a violation of conservation of angular momentum?

When there is a violation of conservation of angular momentum, it means that the total angular momentum of a system has changed without any external torques acting on it. This could be due to external forces or torques that were not accounted for, or due to an error in the measurements.

4. What are some examples of violations of conservation of angular momentum?

Some examples of violations of conservation of angular momentum include the precession of a spinning top, the motion of a spinning gyroscope, and the orbits of planets around the sun. These violations can be explained by the presence of external torques, such as friction or gravitational forces.

5. How is the violation of conservation of angular momentum important in everyday life?

The violation of conservation of angular momentum is important in everyday life because it allows us to understand and predict the behavior of objects in motion. It also helps us to design and improve technologies, such as gyroscopes and satellites, that rely on the principles of angular momentum for their functioning.
