angular kinetic energy
kâruž-e jonbeši-ye zâviye-yi
Fr.: énergie cinétique angulaier
Same as → rotational energy.
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.
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.
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.
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.
Fr.: potentiel cinétique
Same as → Lagrangian function.
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
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.
