释义

Definition of inertial in English:

inertial

adjective ɪˈnəːʃ(ə)lɪˈnərʃəl
Physics
  • 1Relating to or arising from inertia.

    〔主物理〕(与)惯性(有关)的;由惯性引发的

    high-speed centrifuges generate large inertial forces
    the inertial load on the motor
    Example sentencesExamples
    • The interesting thing is that, physically, no difference has been found between gravitational and inertial mass.
    • In Newton's theory, all three of these masses - the inertial mass, the active and passive gravitational masses - are equivalent.
    • If its axis were to be suddenly shifted from its normal inclination, inertial forces produced in such a change would literally tear the earth apart.
    • Einstein warmed to the idea that the gravitational field of the rest of the Universe might explain centrifugal and other inertial forces resulting from acceleration.
    • Another way of understanding the situation is to remember the equivalence Einstein explained between gravitational and inertial forces.
    1. 1.1 (of navigation or guidance) depending on internal instruments which measure a craft's acceleration and compare the calculated position with stored data.
      (导航,制导)惯性的
      Example sentencesExamples
      • The aircraft's navigation system includes an integrated inertial navigation and global positioning INS / GPS system.
      • The aircraft uses a Honeywell inertial navigation system.
      • Inside is a guidance control unit with inertial navigation and global positioning systems.
      • The missile has new GPS / INS (global positioning / inertial navigation) guidance and kinetic warhead.
      • A rocket's inertial guidance system measures acceleration along three principal directions.
    2. 1.2 (of a frame of reference) in which bodies continue at rest or in uniform straight motion unless acted on by a force.
      (参照系)惯性的
      the laws of physics take the same form in all inertial frames
      Example sentencesExamples
      • The rest-mass of a body is the inertial mass of that body when it is at rest relative to an inertial frame.
      • Mach had stated a principle that local inertial frames of reference were determined by the large scale distribution of mass in the universe.
      • Photons, according to the special theory of relativity, move in vacuum with the same speed in all inertial frames of reference.
      • A reference frame in which star motion is ignored and the stars are assumed to be at rest is approximately an inertial reference frame and is often adequate for many purposes.
      • Simple laws apply to constant motion in a straight line (an inertial frame of reference).
