Morphology

gravity + gradient

The meaning 'difference in gravitational force across space' is directly and compositionally derivable from 'gravity' (attraction/force) + 'gradient' (a change or rate of change). Although it is a technical physics term, the semantic combination follows a standard and cross-linguistically common compositional pattern, so a B1 learner who knows both constituents can infer the core meaning.

Etymology

The term gravity gradient starts from the picture of gravity, the pull that draws things, and gradient, a word for a small 'change' across space. Imagine a long satellite where one end is pulled a bit more than the other; that 'difference in pull' is the gravity gradient, and that is why the term describes how gravity changes and affects tides and satellites.
