Relative Velocity

  1. Oct 29, 2008 #1
    The problem I am facing is conceptual. I come across many questions in which they say that the velocity of a person or boat is say 3 m/s with respect to water. Then they give the stream velocity.

    whats the use of the stream velocity when I know the velocity of boat or swimmer with respect to water??? Moreover in certain books, I have seen that the subtract the stream velocity from the horizontal component of the swimmer's or boat's velocity(wrt to water) to calculate the drift. I am totally confused.
    Please explain to me 3 terms in more detail:
    1)Velocity of river with respect to ground
    2)Velocity of swimmer with respect to river/water
    3)Velocity of swimmer with respect to ground
