This brief note addresses a common confusion in continuum mechanics, particularly in axially moving beams, strings and plates, where certain terms arising from the material derivative are mistakenly labeled as “Coriolis acceleration” due to their mathematical similarity to the Coriolis expression. We clarify this misinterpretation using definitions of Coriolis, convective and gyroscopic terms, and show that these terms are not Coriolis accelerations when viewed in fixed reference frames. In addition, we briefly comment on the meaning of the Coriolis inertial force whether it performs mechanical work and how such mislabeling affects teaching, computational modeling and the interpretation of vibration problems.
