Sinking

Hi.

What does it mean for a hot-air balloon to start sinking? How does sinking differ from falling?


Thanks in advance

It's losing altitude in either case. 'falling' suggests free fall; 'sinking' suggests less downward acceleration than that. A hot-air balloon has some buoyancy that a rock would not have, so it doesn't fall as fast.

  • Water also exhibits buoyancy that prevents free fall, so the word 'sink' is used most often for objects that are descending in water.
  • The ship started to sink.
