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
