Laws of Conservation

The laws of conservation in rigid body mechanics refer to principles that state certain physical quantities remain constant in a closed system, unless acted upon by an external force. The most common examples include the conservation of linear momentum, which means the total momentum of a group of objects remains unchanged if no outside force influences them; and the conservation of angular momentum, where the rotation of an object remains constant unless a torque is applied. These laws help us predict the behavior of objects in motion and are fundamental to understanding mechanics and dynamics.
