Free Body Diagram of a Fish Swimming

  1. Apr 27, 2008 #1
    I have this project to do; it's of a free body diagram of a swimming fish. But I can't seem to find any good sites that give much info about a fish swimming. All the sites come up as a fish out of water, or a person swimming. Does anyone know sites that may help, or the forces that act on the fish?

    Have you talked about fluid pressure or buoyancy in your course yet? That will be important in working out the force diagram. What one force do you know has to be acting on the fish?

    The forces on a person swimming will be the same as a fish. Failing that its pretty easy to guess.
