We study the kinematical problem of observation of motion of objects that
move at velocities comparable to the velocity of signals which are used to
determine the velocity and distance of the objects. The main purpose of this
work is to demonstrate the importance of time delay between the emission of
signals and their reception at the observation point. The simplest cases are
considered, i.e., rectilinear motion and assuming the observational point at the
path of the moving object. Sound and light signals are considered to transmit
the information on the motion. The results relating to the motion at constant
velocity and for the acceleration due to a constant force are presented.
