What branch of fluid mechanics deals with the forces exerted by liquids in motion?

The branch of fluid mechanics that focuses specifically on the forces exerted by liquids in motion is hydrodynamics. This field studies the behavior of fluids in motion and includes the analysis of flow patterns, pressure changes, and the interactions between fluids and solid boundaries.

Hydrodynamics is essential for understanding various applications, such as the design of hydraulic systems, the stability of ships, and the flow of rivers. It involves principles that help predict how fluids will behave under different conditions, which is crucial for engineers working in environments where fluid movement is a significant factor.

In contrast, hydraulics is a broader term that encompasses both fluid dynamics and fluid statics (the study of fluids at rest). Pneumatics focuses on the behavior of gases rather than liquids. Fluid statics, while an important aspect of fluid mechanics, deals solely with fluids at rest and does not account for the forces involved in motion, making it distinct from hydrodynamics.
