In a manner relating to or caused by centrifugal force; moving or acting in an outward direction from a center.
From centrifugal adjective plus adverbial suffix -ly. Centrifugal itself comes from Latin centrum and fugere, literally meaning 'center-fleeing,' describing the apparent outward force in rotating systems.
What's wild is that centrifugal force isn't actually a 'real' force in physics—it's what we perceive when we're in a rotating reference frame, yet scientists use this adverb constantly because it's so useful for describing motion in everyday rotating systems.
