Pohyb

Pohyb is a Czech noun meaning movement or motion. It denotes the change of position of a body over time and can refer to physical movement, biological locomotion, or the motion of objects in abstract or mechanical contexts. In everyday language, pohyb describes actions such as walking, driving, or shifting position.

The word is derived from the Czech verb hýbat, to move, through the noun-forming process with the suffix -b. It is closely related to other Slavic terms for motion and appears in compounds such as pohybový, meaning movement-related.

In science, pohyb refers to the concept of motion as studied in physics. It encompasses kinematics, the description of position, velocity, and acceleration, and dynamics, the study of the forces that cause motion. Key quantities include posunutí (displacement), rychlost (velocity or speed), and zrychlení (acceleration). A body’s pohyb is analyzed in relation to a reference frame and may involve trajectories described by dráha or path, such as straight-line or circular motion. Newton’s laws provide a framework for predicting how forces affect pohyb.

In biology, pohyb covers locomotion produced by muscles or cellular mechanisms, including muscular contraction, ciliary movement, and flagellar propulsion. In everyday life and sport, pohyb is central to movement efficiency, exercise, and dance.

Related terms include pohybový (movement-related) and the verbs pohybovat se or hýbat, meaning to move.
