What does mechanics mean?
Mechanics is the branch of physics concerned with motion, force, and the behavior of physical objects. The term also has a practical, general meaning: the principles, details, or structure that make a machine, process, or system work. For example, someone might study the mechanics of an engine, the mechanics of a game, or the mechanics of a particular business model. In these extended senses, mechanics suggests the underlying mechanism and the way its parts interact, often with the implication that the subject can be analyzed systematically. The plural of mechanic, meaning a repair worker, is also a valid use, especially in British and Commonwealth English. Mechanics is consequently a versatile word that links a formal scientific discipline with everyday descriptions of how things function. Its related terms, including mechanism, mechanical, and mechanize, reflect its long connection with the Greek idea of a machine or contrivance.
The branch of physics concerned with the motion and behavior of physical objects under the action of forces.
"Newton formulated foundational principles of classical mechanics."
This is the formal scientific sense and is usually treated as an uncountable field name in phrases such as quantum mechanics.
The practical details, principles, or operating mechanisms of a process, system, or activity.
"The team struggled to understand the mechanics of the new voting system."
This sense is common in general English and often implies a detailed or systematic understanding.
The structure and functioning of a machine or mechanical system, especially as observed in motion.
"The instructor demonstrated the mechanics of the engine on a cutaway model."
This sense is especially associated with machinery, vehicles, clocks, and other physical mechanisms.
Plural of mechanic, referring to people who repair and maintain vehicles or machinery.
"The mechanics replaced the worn brakes before the rally."
This usage is particularly established in British and Commonwealth English; in American English, mechanic is more often used for one individual.
Mechanics is already plural in its standard form. As the plural of mechanic, it refers to repair and maintenance workers; as a field or general concept, it commonly functions as a plural noun in phrases such as quantum mechanics and the mechanics of change.
"The mechanics inspected the engine, and the engineers analyzed the mechanics of the failure."
Mechanics can name both a branch of physics and the hidden rules that make a machine, game, or system work.

Etymology of mechanics
Mechanics comes from the plural of mechanic, a word originally derived from Latin mechanicus, itself from Greek mēchanikos, meaning “of or relating to machines.” The underlying Greek mēchanē referred to a machine, contrivance, or device. By the sixteenth century, mechanics was in use for the science of motion and also for practical machine work; the modern scientific sense developed through its association with mechanical philosophy and later with the branch of physics called mechanics.

How mechanics is actually used
In scientific contexts, mechanics is a formal term associated with the study of motion and force. In general usage, it often means the practical details of how something works. As a plural referring to people, it is more common in British and Commonwealth English than in US English, where mechanic is generally used in the singular for an individual worker.
Easily confused with mechanics
A mechanic is a person trained to repair and maintain machines, whereas mechanics is usually a field of science, a set of operating principles, or the plural of mechanic.
A mechanism is a particular system or arrangement of parts that produces an action or result, while mechanics refers more broadly to the principles, motion, or operating details involved.
