The study of liquids in motion is critical in several scientific fields. Known as fluid dynamics, this branch of science focuses on understanding the properties of liquids as they move and interact with objects. Synonyms for this term include hydrodynamics, fluid mechanics, and flow dynamics. Hydrodynamics is more specific to the study of water, while fluid mechanics encompasses both liquids and gases. Flow dynamics, on the other hand, refers to the study of how fluids move in response to external forces. Regardless of the term used, the science of liquids in motion plays a crucial role in many applications, from designing efficient pipelines to understanding weather patterns.
