Morphology
The adjective 'centripetal' literally means 'directed toward a center' and 'force' means an influence, so a learner who knows both constituents can compose them as an influence that pulls toward a center. This physical-to-social mapping (a force pulling things together) is a straightforward, regular metaphor and is cross-linguistically plausible, so the figurative meaning is directly derivable from the parts.
Etymology
Centripetal force comes from Latin parts centri- ('center') and petere ('to seek'), so it literally means 'seeking the center'. In a circle, imagine a force pulling an object toward the middle, and that image explains why the phrase means a force toward the center.
