Just as we may plot the position-time graph or the displacement-time graph of a particular motion, so we may plot a velocity-time graph for that motion. By convention, velocity is plotted on the vertical axis (since velocity is the dependent variable) and time (the independent variable) is plotted on the horizontal axis. In the special case of uniform motion, the velocity-time graph takes a particularly simple form - it is just a horizontal line, i.e. the gradient is zero. Examples are

Heavy rain periodically causes floods which may wash a large part of a population out to sea; occasional droughts cause populations to perish when streams dry out. Like all organisms, guppies are attacked by a rich variety of parasites and diseases. Of most interest to us in this discussion is that guppies are preyed u
