SUMMARY

The discussion focuses on understanding Coriolis forces and centripetal forces within a cylindrical coordinate system. It establishes that pseudo forces, defined as the negative of mass times acceleration, are crucial for analyzing motion in rotating frames. The Coriolis force is linked to the velocity of an object relative to the rotating frame, while the acceleration computed in cylindrical coordinates is centripetal. The key takeaway is that while centripetal acceleration is frame-dependent, the Coriolis force is influenced by the object's velocity.

Pseudo forses arising in a frame are defined as the negative of mass times acceleration of the frame used. now in cylindrical coordinate system if we compute acceleration, we should be able to know completely the corilis and centripetel forses.
However my problem is I don't understand how can we know coriolis forse by computing acceleration in cylindrical system since it (coriolis forse) involves velocity of the object, w.r.t. the rotating frame, and is independent of the frame whose acceleration we are computing using cylindrical co-ordinate system.

The acceleration of the frame is centripetal.

Hi mritunjay! :smile:

Pseudo (fictional) forces are inertial forces, meaning that the acceleration due to an inertial force is independent of the mass.

But it can depend on velocity.
