The fluid. deformation: velocity gradients can cause deformation, “stretching” resulting in a change in volume of the fluid element. rate of change for one direction: for all 3 directions: the shape does not change, “linear deformation” the linear deformation is zero for incompressible fluids. = 0. The study of motion can be divided into two parts. kinematics concerns the description of motion, while dynamics inquires into its causes. in elementary mechanics we are concerned with the motion of solid bodies, e.g., orbiting planets, billiard balls and the apple that supposedly fell on newton’s head. in these cases the motion is simple to. Let x, y and z denote the space coordinates and t the time. let v be the resultant velocity at any point in space in a fluid body. let u, v and w be the components of the resultant velocity v at any point in the directions of the x, y and z axes. fig. 6.1 illustrates the notations.
