# Inertial force

From AMS Glossary

(Redirected from Inertial forces)

## inertial force

- (Or inertia force.) A force in a given coordinate system arising from the inertia of a parcel moving with respect to another coordinate system.

For example, the Coriolis acceleration on a parcel moving with respect to a coordinate system fixed in space becomes an inertial force, the Coriolis force, in a coordinate system rotating with the earth.
