What is mécanique?

Mécanique, translating directly to 'mechanics' from French, is the branch of physics concerned with the motion of bodies under the action of forces, including the special case in which a body remains at rest. It's a fundamental field underpinning many engineering disciplines. Mechanics explains how things move, why they move, and the forces involved. It is commonly used in the design of machines, structures, and vehicles, and it is critical in analyzing their performance and stability.
