One-word substitution (physics direction): Select the precise term for a force or tendency that moves away from the centre or axis of rotation. Context: Contrast with the inward-directed term used in circular motion. Instruction: Choose the correct option.

Given data

• Meaning: tending to move away from the centre/axis.
• Options: Centrifugal, Centripetal, Axiomatic, Awry.

Concept / Approach
Centrifugal (from Latin centrum ‘‘centre’’ + fugere ‘‘to flee’’) denotes outward tendency; centripetal (‘‘seeking the centre’’) denotes inward pull. The other words are unrelated.

Elimination
Centrifugal — outward from the centre; correct. ✅Centripetal — toward the centre; opposite meaning. ❌Axiomatic — self-evident; not directional. ❌Awry — askew/amiss; not a physical tendency. ❌

Example
‘‘A rotating drum can fling water droplets outward by centrifugal effect.’’

Final Answer
Centrifugal
