angular kinetic energy
  کاروژ ِ جنبشی ِ زاویه‌ای   
kâruž-e jonbeši-ye zâviye-yi

Fr.: énergie cinétique angulaier   

Same as → rotational energy.

angular; → kinetic; → energy.

isokinetic angle
  زاویه‌ی ِ ایزوجنبشی   
zâviye-ye izojonbeši

Fr.: angle isocinétique   

Adaptive optics: The angle over which wavefront phases become de-correlated by 1 radian rms due to → tip-tilt alone. It is defined analogously to the → isoplanatic angle.

iso-; → kinetic; → angle.

kinetic
  جنبشی   
jonbeši (#)

Fr.: cinétique   

Of or relating to motion; caused by motion; characterized by movement.

From Gk. kinetikos "moving, putting in motion," from kinein "to move," → kinematics.

Jonbeši, adj. of jonbeš, verbal noun of jonbidan, → move.

kinetic energy
  کاروژ ِ جنبشی   
kâruž-e jonbeši

Fr.: énergie cinétique   

The energy which a body possesses as a consequence of its motion, defined as one-half the product of its mass m and the square of its speed v, i.e. 1/2 mv2.

kinetic; → energy.

kinetic helicity
  پیچاری ِ جنبشی   
picari-ye jonbeši

Fr.: hélicité cinétique   

In fluid mechanics, a quantity that describes helical flow. It is defined by the integrated scalar product of the velocity field and the → vorticity: KK = ∫ dVu . ( x u). In the absence of magnetic field, this quantity is conserved by the → Euler equation. See also → magnetic helicity.

kinetic; → helicity.

kinetic potential
  توند ِ جنبشیک   
tavand-e jonbešik

Fr.: potentiel cinétique   

Same as → Lagrangian function.

kinetic; → potential.

kinetic temperature
  دمای ِ جنبشی   
damâ-ye jonbeši (#)

Fr.: température cinétique   

The temperature of a gas defined in terms of the average kinetic energy of its atoms or molecules.

kinetic; → temperature.

kinetic theory of gases
  نگره‌ی ِ جنبشی ِ گاز‌ها   
negare-ye jonbeši-ye gâzhâ (#)

Fr.: théorie cinétique des gaz   

A theory that explains macroscopic properties of gases, such as pressure, temperature, or volume, by considering their molecular composition and motion.

kinetic; → theory; → gas.
