## Centrifugal Force

 Quote by DrStupid I am speaking about centrifugal force. I never heard of "reactive centrifugal force". What action would a centrifugal force react to?
The reactive centrifugal force is a reaction to a centripetal force. It's not a term I would ever use. (But some do: Reactive centrifugal force)

 Quote by Emilyjoint Just identify real forces (centripetal and centrifugal are not real forces) find the resultant then use F =ma
I wouldn't put centripetal and centrifugal forces in the same boat as being not real. While I agree that 'centripetal force' is just a term signifying the net force that produces centripetal acceleration (and not a new kind of force), the forces that make up the centripetal force in any given situation are usually quite real (string tension, gravity, etc.) and have 3rd law pairs (like any interaction force). But centrifugal force (using the standard terminology) is never 'real'--it's not an interaction with any other body.
