  • zh逃逸速度,指物体摆脱天体引力场所需的最小速度,无需额外加速;也比喻达到临界动量或独立性的临界点。

The minimum speed needed for an object to break free from the gravitational pull of a celestial body without further propulsion; also used metaphorically to describe reaching a critical point of momentum or independence.

  1. Physics conceptC1formal

    The minimum speed an object needs to break free from a celestial body's gravitational pull without further propulsion.

    • Calculating escape velocity depends on the mass and radius of the planet.
  2. Metaphorical usageB2informal

    The critical point or speed needed to break away from a limiting situation, routine, or system.

    zh临界点

    • The startup finally reached its escape velocity and became profitable.
    • She felt she needed to achieve escape velocity from her boring job.
