Cool. I notice that something dropped from the top accelerates downwards. But something released at the bottom doesn't seem to accelerate noticeably upwards. Even with drag, a bouyant object should accelerate towards the suface, shouldn't it?
- santialbo 6y agoNote drag increases with speed. So objects accelerate until drag negates buoyancy and then it just goes upwards at a costant speed.
- hermitcrab 6y agoI guess that the 'terminal velocity' is quite slow as the difference between water and ice buoyancy is small.
