full_question: This force names the cross-terms composed of the product of two different generalized coordinates inthe Euler-Lagrange equations. This force stabilizes the fourth and fifth Lagrange points. It opposespressure in geostrophic flow. Because this force always acts perpendicular to the velocity of the bob at theend of (*) Foucault's pendulum, it does no work on the bob. The magnitude of this force is given as two times thecross product of an angular velocity and a linear velocity. The namesake coefficient of this force is proportional tothe sine of the latitude and the rotation rate of Earth. It explains why a ball thrown from a carousel appears todeflect, depending on the hemisphere. For 10 points, name this fictitious force seen in rotating reference frames.
first_sentence: This force names the cross-terms composed of the product of two different generalized coordinates inthe Euler-Lagrange equations.
raw_answer: Coriolis force [or the Coriolis effect]
