Centrifugal Force

Centrifugal force, abbreviated as \(F_c\) or \(F_{cf}\), is when a force pushes away from the center of a circle, but this does not really exist.  When an object travels in a circle, the object always wants to go straight, but the centripetal force keeps the object traveling along an axis of rotation.

 

Centrifugal force by Angular Velocity formula
\(\large{ F_c =  m \; \omega^2 \; r  }\)
Symbol	English	Metric
\(\large{ F_c }\) = centrifugal force	\(\large{lbf}\)	\(\large{N}\)
\(\large{ \omega }\)   (Greek symbol omega) = angular velocity	\(\large{\frac{deg}{sec}}\)	\(\large{\frac{rad}{s}}\)
\(\large{ m }\) = mass	\(\large{lbm}\)	\(\large{kg}\)
\(\large{ r }\) = radius from the origin	\(\large{ft}\)	\(\large{m}\)

 

Centrifugal force by Tangential Velocity formula
\(\large{ F_c = \frac { m \; v_t^2 }{ r } }\)
Symbol	English	Metric
\(\large{ F_c }\) = centrifugal force	\(\large{lbf}\)	\(\large{N}\)
\(\large{ m }\) = mass	\(\large{lbm}\)	\(\large{kg}\)
\(\large{ r }\) = radius from the origin	\(\large{ft}\)	\(\large{m}\)
