I am trying to build a vocabulary describing things falling in water. There are three aspects to it: a) the act of dropping or throwing the object; b) the movement of the object in the water, which could sink or float; c) the movement of water because of the object's impact. The objects could be anything ranging from a piece of cork to an asteroid for all I care.
I have already used some terms: drop/throw, sink/float. I made a little search in thesaurus but, here, I would like to leverage the sensitivity of the community fellows to nuances between similar terms. For example: subtle differences, if any, re a between falling, dropping and suchlike; re b, between plunging, diving and suchlike; re c, between splashing, surging, and so forth.
Word suggestions accompanied by such explanations and caveats will be most appreciated.
Note I am not interested in scientific rigour, rather in the descriptive/evocative meaning for a lay readership/audience.
Note The post topic branches off in many possible answers. I do not expect answers with full coverage, for sure. Anyone interested please pick up the aspects that resonate the most.
