# Coriolis Force

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Coriolis force, abbreviated as $$F_c$$, also called compound centrifugal force and deflecting force, is experienced by an object traversing a path in a rotating frame of reference.

## Coriolis Force Formula

 $$\large{ F_c = -2 \; m \; \left( \omega \; v_t \right) }$$

### Where:

 Units English Metric $$\large{ F_c }$$ = Coriolis force $$\large{lbf}$$ $$\large{N}$$ $$\large{ \omega }$$   (Greek symbol omega) = angular velocity $$\large{\frac{deg}{sec}}$$ $$\large{\frac{rad}{sec}}$$ $$\large{ m }$$ = mass $$\large{lbm}$$ $$\large{kg}$$ $$\large{ v_t }$$ = tangential velocity $$\large{\frac{ft}{sec}}$$ $$\large{\frac{m}{s}}$$
