# Coriolis Acceleration

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Coriolis acceleration, abbreviated as $$a_c$$, is caused by Coriolis force.  It always acts perpendicular to the angular velocity and linear velocity.

## Coriolis Acceleration Formula

 $$\large{ a_c = 2 \; v \; \omega \; sin \; \theta }$$

### Where:

 Units English Metric $$\large{ a_c }$$ = Coriolis acceleration $$\large{\frac{ft}{sec^2}}$$ $$\large{\frac{m}{s^2}}$$ $$\large{ \theta }$$ (Greek symbol theta) = angle $$\large{deg}$$ $$\large{rad}$$ $$\large{ \omega }$$   (Greek symbol omega) = angular velocity $$\large{\frac{deg}{sec}}$$ $$\large{\frac{rad}{sec}}$$ $$\large{ v }$$ = velocity $$\large{\frac{ft}{sec}}$$ $$\large{\frac{m}{s}}$$
