Question

the motion of a dolphin in water which motion​

Answer 1

Answer:

To swim, a dolphin bends its tail up and down. As the tail moves, it leaves one space and enters another, and pushes the water in this new space out of the way. As the dolphin keeps moving its tail up and down, it keeps pushing water out of the way.

Answer 2

Drafting in cetaceans is defined as the transfer of forces between individuals without actual physical contact between them. This behavior has long been surmised to explain how young dolphin calves keep up with their rapidly moving mothers. It has recently been observed that a significant number of calves become permanently separated from their mothers during chases by tuna vessels. A study of the hydrodynamics of drafting, initiated in the hope of understanding the mechanisms causing the separation of mothers and calves during fishing-related activities, is reported here.
