Exploring Coriolis vs Centripetal Acceleration

[firavia]

according to the figure attached below , do we have a coriolis acceleration on the slider and why ?

why can't we say that it is a centripital acceleration ?

I want to know the difference between coriolis accelration and centrepetal acceleration ,

cause As I know , coriollis acceleration show's up only if we are studying the object in a rotational frame, why are we concidering here that it is a rotaitonal frame and not an inertial frame ??

I hope someone would answer my question

Firstly, let's define the terms. Coriolis acceleration is the acceleration experienced by an object in a rotating frame of reference, caused by the Coriolis effect. Centripetal acceleration is the acceleration towards the center of a circular path, caused by a centripetal force.

In the figure attached, the slider is moving in a circular path, which indicates that there is a centripetal acceleration acting on it. However, we cannot say for certain if there is also a Coriolis acceleration present without more information about the frame of reference.

The Coriolis effect is only observed in a rotating frame of reference, where there is a non-inertial force acting on the object. In an inertial frame of reference, such as a stationary observer on the ground, the Coriolis effect is not present. Therefore, we cannot definitively say that there is a Coriolis acceleration present in this scenario without knowing if the frame of reference is rotating or not.

To better understand the difference between Coriolis and centripetal acceleration, let's consider an example. Imagine you are on a merry-go-round that is rotating at a constant speed. As you move towards the edge of the merry-go-round, you experience a centripetal acceleration towards the center. However, to an observer standing outside the merry-go-round, you also appear to be experiencing a Coriolis acceleration as you move in a curved path.

In summary, it is important to consider the frame of reference when determining whether there is a Coriolis or centripetal acceleration present. Without more information, we cannot definitively state which type of acceleration is acting on the slider in the figure.
