Relating to the movement of liquids and the forces involved when they are in motion.
The hydrodynamic design of the boat allows it to move quickly through the water.
Hydrodynamic is formed from "hydro-" (from Greek "hydor", meaning water) and "dynamic" (from Greek "dynamis", meaning power or force). The term refers to the forces and motion of fluids, particularly water, emphasizing the power of water in motion.
Think of 'water' ('hydro-') and 'force' ('dynamic') to remember that hydrodynamic relates to the forces of moving water.
