Baris 281:
which can be compared to the equations for the inertial frame:
:<math>F_r = m \ddot r -mr \dot {\varphi}^2 \ </math>
:<math>F_{\varphi} = mr \ddot \varphi +2m \dot r \dot {\varphi} \ .
This comparison, plus the recognition that by the definition of the co-rotating frame at time ''t'' it has a rate of rotation Ω = ''dφ''/''dt'', shows that we can interpret the terms in the acceleration (multiplied by the mass of the particle) as found in the inertial frame as the negative of the centrifugal and Coriolis forces that would be seen in the instantaneous, non-inertial co-rotating frame.
