Conservative System


a mechanical system in which the law of conservation of mechanical energy is valid—that is, the sum of the kinetic energy T and the potential energy P of the system is constant: T + P = const.

An example of a conservative system is the solar system. Under conditions that exist on earth, where the presence of forces of resistance such as friction and drag, which lead to a loss of mechanical energy and its conversion to other forms of energy (for example, heat), is unavoidable, only a rough approximation of a conservative system is possible. For example, a swinging pendulum may be considered a conservative system if friction in the suspension axis and air resistance are disregarded.
