New General Catalogue (NGC) kâtâlog-e harvin-e now Fr.: New General Catalogue A catalogue of 7,840 non-stellar objects compiled by J. L. E. Dreyer
and published in 1888. A further 1,529 objects were listed in a supplement that
appeared seven years later, called the → |

new moon nowmâh (#), mâh-e now (#), andarmâh (#) Fr.: nouvelle lune The Moon's phase when it is at the same celestial longitude as the Sun and thus totally un-illuminated as seen from Earth. |

newton newton (#) Fr.: newton The unit of force in the SI system of units. 1 newton (N) is defined as
the force required to give a mass of 1 kilogram an acceleration of 1 m s Named after Sir Isaac Newton (1642-1727), the English highly prominent physicist and mathematician. |

Newton's color wheel carx-e rang-e Newton Fr.: disque de Newton The arrangement of the seven colors of the rainbow on a disk.
When the disk rotates very fast, the eye cannot distinguish between individual colors and
the disk is perceived as white. This apparatus demonstrates the discovery made by
Newton ( |

Newton's cradle gahvâre-ye Newton Fr.: pendule de Newton A device consisting of a series of equal → |

Newton's disk gerde-ye Newton Fr.: disque de Newton |

Newton's equation hamugeš-e Newton Fr.: équation de Newton In → |

Newton's first law of motion naxostin qânun-e Newtoni-ye jonbeš (#) Fr.: première loi newtonienne de mouvement A body continues in its state of constant velocity (which may be zero) unless it is acted upon by an external force. |

Newton's law of cooling qânun-e sardeš-e Newton Fr.: loi de refroidissement de Newton An approximate empirical relation between the rate of
→ T is the temperature of
the object, T is that of its surroundings, _{s}t is time,
and k is a constant, different for different bodies. |

Newton's law of gravitation qânun-e gerâneš-e Newton Fr.: loi newtonienne de la gravitation The universal law which states that the force of attraction between any
two bodies is proportional to the product of their masses and inversely proportional
to the square of the distance between them:
G
is the → gravitational constant.→ |

Newton's laws of motion qânunhâ-ye jonbeš-e Newton Fr.: lois de mouvement de Newton The three fundamental laws which are the basis of
→ |

Newton's method raveš-e Newton Fr.: méthode de Newton Same as the → |

Newton's rings halqehâ-ye Newton (#) Fr.: anneaux de Newton Colored circular → |

Newton's second law of motion dovomin qânun-e Newtoni-ye jonbeš (#) Fr.: seconde loi newtonienne de mouvement For an unbalanced force acting on a body, the acceleration produced is proportional to the force impressed; the constant of proportionality is the inertial mass of the body. |

Newton's shell theorem farbin-e puste-ye Newton Fr.: théorème de Newton In classical mechanics, an analytical method applied to a material sphere
to determine the gravitational field at a point outside or inside the sphere.
Newton's shell theorem states that:
1) The gravitational field outside a uniform spherical shell (i.e. a hollow ball) is
the same as if the entire mass of the shell is concentrated at the center of the sphere.
2) The gravitational field inside the spherical shell is zero, regardless
of the location within the shell.
3) Inside a solid sphere of constant density, the gravitational force varies linearly
with distance from the center, being zero at the center of mass.
For the relativistic generalization of this theorem,

Newton's third law of motion sevomin qânun-e Newtoni-ye jonbeš (#) Fr.: troisième loi newtonienne de mouvement In a system where no external forces are present, every action force is always opposed by an equal and opposite reaction. |
