Without gravity, the ball would not be in frictional contact with the turntable, but that's as far as any interrelation (or connection) with gravity goes!
The frictional force from the turntable changes both the ball’s linear momentum and its angular momentum, and analysis shows it will undergo circular motion with an angular speed related to the moment of inertia of the ball.
A solid ball of mass m and radius r has a moment of inertia of 2/5mr^2 which results in it circling with an angular speed 2/7th that of the turntable.
The Coriolis effect appears when Newton's laws are transformed to a rotating frame of reference.
The situation to consider in that case is of a ball which is rolled across a rotating turntable.
Relative to the non-rotating frame of reference the ball moves in a straight line, but to an observer in the rotating frame the ball follows a curved path as though some mysterious sideways force was pushing it off its course.
This fictitious or pseudo force is called the Coriolis force.
If you happen to live on the equator, your 'primary motion' through space is approx. 1600Kph 😉
Oh noes, I watched it (a few seconds of it then moving ahead a few minutes), now Youtube is gonna feed me lots of "free energy" videos ...
There's a Facebook page "Multi tech Info" which FB often feeds me. It's got those same sort of videos of making over-the-top "devices" that generate free electric power or free wifi or whatever, using ceramic speaker magnets (often with wire wound around as if it were a toroid transformer), spark plugs, transformers, motors, and more soldered together in bizarre ways, but the contraptions somehow power a light bulb and a fan.
This guy explains EXACTLY how these videos are done. It's longish at 44 minutes, but the payoffs are:
12:44 he just built the device and is trying it out.
33:52 he explains what he REALLY did.

There are lots of gullible people out there, but in this thread we obey the laws of thermodynamics!!

So the speaker magnet is acting as a generator the spring like structure is carring current in some 100a range. Total output actually is 6900w but for safety it is operated at 6000w.
Why is it a fictitious force? Or are you differentiating between ‘effect’ and force?
A fictitious force (AKA inertial force, pseudo force, effective force or reverse effective force) does not arise from any physical interaction between two objects.

Is this 40,000 km / 24 hour ?
40,000/24 km/h
10,000/6
5,000/3
1,666.666666667 km/h
Ahh, inertial frames of reference! There’s a nice little video embedded in the wiki article that makes it clearer in respect of the Coriolis effect.
