escape velocity

• Velocidade mínima necessária para um objeto superar a atração gravitacional de um corpo celeste sem aceleração adicional; também é usada metaforicamente para descrever o momento em que se atinge um ponto crítico de impulso ou independência.

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.

   velocidade de escape

   • The escape velocity from Earth is about 11.2 kilometers per second.
   • Rockets must reach escape velocity to enter outer space.
   • 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.

   Ponto crítico

   • The startup finally reached its escape velocity and became profitable.
   • She felt she needed to achieve escape velocity from her boring job.
   • The project gained enough momentum to reach escape velocity and succeed.
