1. relating to the motion of fluids (especially water) and the forces acting on objects moving through them
Usage: commonly used in physics and engineering contexts
2. designed or shaped to move efficiently through water or other fluids with minimal resistance
Usage: often applied to vehicles, vessels, and animal bodies

Examples

• The submarine's hydrodynamic hull reduces drag as it moves through the ocean.
• Engineers studied the hydrodynamic forces acting on the bridge during the flood.
• Dolphins have evolved hydrodynamic bodies that allow them to swim at high speeds.
• The car's hydrodynamic design helps it achieve better fuel efficiency.
• Hydrodynamic principles are essential in the design of modern ships.
• The research team conducted hydrodynamic tests in a water tunnel.
• Fish have naturally hydrodynamic shapes that minimize water resistance.
