How does the conservation of momentum symmetry apply in the context of physical interactions between objects?
The conservation of momentum symmetry states that in a closed system, the total momentum before a physical interaction between objects is equal to the total momentum after the interaction. This means that the combined momentum of all objects involved remains constant, showing that momentum is conserved in the interaction.

What is a sentence using the law of conservation of momentum?
When two vehicles collide and come to a stop, the total momentum of the vehicles before the collision is equal to the total momentum after the collision, in accordance with the law of conservation of momentum.
What are the six principle of physics?

How does Noether's theorem relate to the conservation of energy?
Noether's theorem states that for every symmetry in a physical system, there is a corresponding conservation law. In the case of energy conservation, the theorem shows that the symmetry of time translation (the laws of physics remain the same over time) leads to the conservation of energy. This means that energy cannot be created or destroyed, only transformed from one form to another.
How did Noether show how the two concepts are related?
Noether demonstrated the relationship between symmetry and conservation laws in physics through her groundbreaking theorem, which states that for every continuous symmetry in a physical system, there exists a corresponding conservation law. This theorem has had a profound impact on the field of theoretical physics.
What is the definition of time symmetry and how does it relate to the fundamental principles of physics?
Time symmetry refers to the idea that the laws of physics remain the same regardless of whether time is moving forward or backward. This concept is closely related to the fundamental principles of physics, such as the conservation of energy and the principle of causality. Time symmetry suggests that the behavior of physical systems is consistent and predictable, regardless of the direction of time.

Conservation is a LAW therefore true but I want to know why it happens what is the theory that explains it?
You mention conservation in general; there are several conservation laws, like conservation of energy, of linear momentum, of rotational momentum, of electrical charge, and others. This is originally based on experience - for example, no cases are known where the linear momentum is violated. However, these conservation laws (or many of them?) can be explained with Noether's Theorem. This is some very advanced math (for me, at least), but basically, it states that for every symmetry in nature, there is a corresponding conservation law. For example, the fact that the laws of physics are the same today as a year ago (they don't change over time) is related to the Law of Conservation of Energy; the Law of Conservation of Momentum is related to a symmetry with respect to position (the laws of nature are the same here as on the Moon), and the Law of Conservation of Rotational Momentum is related to a symmetry with respect to rotation (if you rotate an experimental apparatus, the results won't change).

What is amalie Emmy noether known for?
She was mainly known for Noether's Theorem, which is often quoted nowadays, when talking about conservation of energy. Noether's Theorem makes it possible to relate several conservation laws with corresponding laws of symmetry in the Universe. In the case of energy conservation, this is related to the fact that physical laws don't change over time. In other words, if energy conservation weren't valid, then physical laws would change over time! Similarly, the law of Conservation of Momentum is related to another symmetry: physical laws are the same anywhere in the Universe. Please note that a detailed understanding of Noether's Theorem requires some pretty advanced math.
Angular momentum about the center of the planet is conserved?
Angular momentum is conserved when there is no external torque acting on a system. For a planet, the net torque acting on it is negligible, so its angular momentum about its center will be conserved unless acted upon by an external force. This conservation principle is a consequence of the rotational symmetry of the system.

What is the significance of the c2v character table in the study of molecular symmetry?
The c2v character table is important in the study of molecular symmetry because it helps identify the symmetry elements and operations present in a molecule. This information is crucial for understanding the physical and chemical properties of the molecule, as well as predicting its behavior in various reactions and interactions.
How is the law of conservation of charge similar to the law of conservation of energy?
The similarity is the "conservation" part - there is something that doesn't change over time.And of course, according to Nöther's theorem, that is the result of a symmetry of nature. * In the case of conservation of energy, time symmetry (the fact that the laws of physics don't change over time). * In the case of conservation of charge, gauge invariance.

How is Noethers Theorem used today?
Noether's Theorem is fundamental in modern physics as it connects symmetries and conservation laws, providing a powerful framework for analyzing physical systems. It is extensively used in fields such as particle physics and cosmology, where symmetries underlie the conservation of energy, momentum, and charge. Additionally, the theorem aids in the formulation of theories like the Standard Model and in understanding phenomena like spontaneous symmetry breaking in the early universe. Its implications extend to various areas of theoretical physics, making it a cornerstone of contemporary scientific inquiry.
