Therefore, a domain joining a tree immediately has trust relationships established with every domain in the tree. A Forest A forest is a collection of multiple trees that share a common global catalog, directory schema, logical structure, and directory configuration. Forest has automatic two way transitive trust relationships. The very first domain created in the forest is called the forest root domain.
The law of conservation of momentum states that the total momentum of a group of objects does not change unless outside forces act on the objects. The law of conservation of momentum states that the total momentum of a group of objects does not change unless outside forces act on the objects.
In this case, must be zero, implying that the total angular momentum of a system is constant. We can state this verbally: If no net external torque acts on a system, the total angular momentum of the system remains constant. This statement describes the conservation of angular momentum. It is the third of the major conservation laws encountered in mechanics (along with the conservation of energy and of linear momentum). There is one major difference between the conservation of linear momentum and conservation of angular momentum. In a system of particles, the total mass cannot change. However, the total moment of inertia can. If a set of particles decreases its radius of rotation, it also decreases its moment of inertia.
