What is fluid dynamics?

Fluid dynamics refers to the study of the behavior and motion of fluids, which includes both liquids and gases. This field of study focuses on how fluids interact with their surroundings, how they move under various forces, and how they respond to changes in pressure and temperature. This encompasses a wide range of applications, from predicting weather patterns to designing aircraft and understanding natural phenomena like ocean currents.

The definition of fluid dynamics illustrates its broad scope beyond just liquids, which is why the option specifying the study of fluid motion is the most accurate. Understanding fluid dynamics is crucial in various engineering disciplines, including mechanical, civil, and aerospace engineering, as it helps in designing systems and predicting the performance of various applications involving fluid flow.
