单词 terminal velocity
释义

terminal velocity

noun Physics
The constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration.Initially they will accelerate, but they will soon reach a constant terminal velocity when the air resistance around them offsets their downward acceleration....
  • Because air resistance also depends on the shape of the object and so by tucking in your arms and legs you can reach a faster terminal velocity than if your arms and legs are spread out.
  • He starts to fall, picks up speed, and accelerates to near his terminal velocity in the first 10 seconds.
