Scientists who study mechanics are called physicists, specifically those specializing in classical mechanics or theoretical mechanics.

However, the term "mechanics" can encompass a broader range of fields, so other scientists might also be involved:

* Engineers apply mechanics principles to design and build machines, structures, and systems.

* Material scientists study the mechanical properties of materials.

* Biomechanists study the mechanics of living organisms.

So, while "physicists" are the core scientists of mechanics, various other disciplines utilize and contribute to this fundamental field.
