nongravitational positive

Morphology

nongravitational = gravitational (transparent) = non + gravity + al

The adjective is formed by straightforward negation (non-) of 'gravitational'; 'gravitational' itself is a clear adjective related to 'gravity' + -al.

Etymology

Nongravitational is non- 'not' plus gravitational, which comes from gravity, a word that once meant 'heaviness'. So nongravitational describes forces or effects that are 'not caused by gravity'.
