The study of forces on air around a body in motion is called Aerodynamics.

Here's a breakdown:

* Aero refers to air.

* Dynamics refers to the study of motion and forces.

Aerodynamics focuses on understanding:

* How air flows around objects.

* The forces that air exerts on those objects (lift, drag, thrust).

* How to design objects to minimize drag and maximize lift.

This field is crucial for designing everything from airplanes and rockets to cars and bicycles.
