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.
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.

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.
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.
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.

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).

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 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.

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.

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.
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.

Forbidden transitions are transitions in a physical system that are not allowed according to selection rules, usually due to conservation laws or symmetry considerations. Allowed transitions are transitions that are permitted by the selection rules and can occur in a given physical system.
