Cgewicht

Cgewicht is a term used in theoretical discussions and educational contexts to denote an effective weight experienced by a mass when viewed from a non-inertial reference frame. It aims to highlight how weight can change with motion and rotation, rather than to introduce a separate physical unit.

The word combines the Dutch woord gewicht, meaning weight, with a prefixed C that is often interpreted as standing for concepts such as centrifugal, composite, or context-dependent. It is not an officially adopted SI unit and is not widely standardized in peer-reviewed physics literature. In practice, Cgewicht functions as a label for the weight calculated using an effective gravitational acceleration in a given frame.

Definition and calculation: In a frame that accelerates linearly with acceleration a and rotates with angular velocity ω, the effective gravitational acceleration g_eff is formed by combining real gravity g with inertial contributions such as the linear acceleration and centrifugal terms (for example, g_eff ≈ g + a + ω^2 r in appropriate directions). The Cgewicht of a mass m is then defined as W_C = m g_eff. Because g_eff depends on the observer’s frame, Cgewicht is inherently frame-dependent and does not constitute a universal constant.

Usage and context: Cgewicht is used mainly in thought experiments, classroom demonstrations, and discussions of artificial gravity in rotating habitats, elevators, or spacecraft. It helps illustrate concepts like apparent weight, inertial forces, and design considerations where effective gravity varies with position or motion.
