Is the Coriolis force actually experienced by an object, or is the object simply deflected in its path?
By experience, do you mean the object experiences resistance to the force, in the same way an object experiences inertialanuttarasammyak said:Coriolis force is experienced by, and thus deflects the path of the object in rotating frame of reference.
I would say that it is the Coriolis pseudoforce. It is the result of inertia.Ranku said:Is the Coriolis force actually experienced by an object, or is the object simply deflected in its path?
In rotating frame of reference centrifugal force and Coriolis force deflect the path of free moving object from the straight line. The free moving objects on the deflected path under centrifugal and Coriolis force get no stress. Even very fragile objects keep their shapes. It is obvious because they are at rest or moving at a constant speed in IFR.Ranku said:do you mean the object experiences resistance to the force, in the same way an object experiences inertial
force in response to an applied contact force?
To clarify, the objects the not feeling the Coriolis force, even though they are deflected by the force?anuttarasammyak said:In rotating frame of reference centrifugal force and Coriolis force deflect the path of free moving object from the straight line.

What do you mean by "feeling"? In frames where the Coriolis force exists it's like gravity - you can't measure it in any way, except that your velocity with respect to points that are fixed in the rotating frame is varying or you feel a contact force from such a fixed point.Ranku said:To clarify, the objects the not feeling the Coriolis force, even though they are deflected by the force?
Yes, that is what I was trying to clarify, the fact that the inertial mass of the object doesn't feel the Coriolis force, just like gravitational mass of an object doesn't feel the gravitational force, when it is in gravitational freefall. On the other hand, gravitational force is felt, when there is a counteracting contact force, such as the 'normal' force, when the object is resting on the ground; similarly, Coriolis force would also be felt if there is a counteracting contact force, in the form of an attachment to a fixed point on the rotating disc.Ibix said:What do you mean by "feeling"?

You still don't feel either gravitational force nor Coriolis force in those circumstances - you feel the force from the contact point. If you adopt the non-inertial coordinates in which the the contact point (the floor or the rotating wall or whatever) is at rest, you interpret that contact force as being a reaction to some other force which you call gravity/Coriolis, but you can always adopt an inertial frame and interpret it as a contact force created by the non-inertial motion of the contact point.Ranku said:On the other hand, gravitational force is felt, when there is a counteracting contact force, such as the 'normal' force, when the object is resting on the ground; similarly, Coriolis force would also be felt if there is a counteracting contact force, in the form of an attachment to a fixed point on the rotating disc.
Minor nitpick here.Ranku said:Coriolis force would also be felt if there is a counteracting contact force, in the form of an attachment to a fixed point on the rotating disc.
