  پتایانش، پتایش   
patâyâneš, patâyeš

Fr.: conservation, préservation   

The act or an instance of conserving.

Verbal noun of → conserve.

conservation law
  قانون ِ پتایش   
qânun-e patâyeš

Fr.: loi de conservation   

A general statement that a → physical quantity, such as → energy, → mass, → momentum, or → electric charge is unchanged in an → interaction occurring within a → closed system. See also:
conservation of charge, → conservation of energy, → conservation of mass, → conservation of mass and energy, → conservation of matter, → conservation of momentum, → conservation of probability, → parity conservation, → conservative field.

conservation; → law.

conservation of charge
  پتایش ِ بار   
patâyeš-e bâr

Fr.: conservation de charge   

In any given → frame of reference, → electric charge is neither created nor destroyed. This → law must not be confused with → charge invariance.

conservation; → charge.

conservation of energy
  پتایش ِ کاروژ   
patâyeš-e kâruž

Fr.: conservation d'énergie   

The → principle whereby the → total energy of a → closed system remains → constant. This means that energy can neither be created nor destroyed. See also the → first law of thermodynamics.

conservation; → energy.

conservation of mass
  پتایش ِ جرم   
patâyeš-e jerm

Fr.: conservation de masse   

A → principle of → classical physics whereby → matter can be neither created nor destroyed. Matter can, however, be → converted into → energy, as predicated by the theory of → special relativity. Also called → conservation of matter.

conservation; → mass.

conservation of mass and energy
  پتایش ِ جرم و کاروژ   
patâyeš-e jerm o kâruž

Fr.: conservation de masse et d'énergie   

A principle, resulting from Einstein's theory of → special relativity whereby in any → closed system the sum of mass and energy remains → constant.

conservation; → mass; → energy.

conservation of matter
  پتایش ِ ماده   
patâyeš-e mâddé

Fr.: conservation de matière   

Same as → conservation of mass.

conservation; → matter.

conservation of momentum
  پتایش ِ جنباک   
patâyeš-e jonbâk

Fr.: conservation de quantité de mouvement   

A fundamental law of physics which states that the momentum of a → physical system does not change in the course of time if there are no external forces acting on the system. It is embodied in → Newton's first law. This principle shows that the interaction of bodies composing a → closed system leads only to an exchange in momentum between the bodies but does not affect the motion of the system as a whole. More specifically, interactions between the composing bodies do not change the velocity of the system's → center of mass.

conservation; → momentum.

conservation of probability
  پتایش ِ شوانایی، پایندگی ِ ~   
-patâyeše šavânâyi, pâyandegi-ye ~

Fr.: conservation de probabilité   

A principle according to which the sum of probabilities of all possible states that might come out of an initial state equals the probability of the initial state.

conservation; → probability.


Fr.: conservatisme   

The disposition, or political philosophy, to preserve the existing or traditional order and oppose radical change.

conservative; → -ism.
