Centirpetal And Centrifugal Forces

AI Thread Summary
The discussion centers on the distinction between centripetal and centrifugal forces, with a proposal to use more specific terms like gravipetal-gravifugal and cohesipetal-cohesifugal. Participants debate the accuracy of describing astronaut levitation in orbit, arguing that it is misleading to attribute this to centrifugal force, advocating instead for the term gravifugal force as a clearer representation of the reaction to gravitational pull. The conversation highlights the importance of precise terminology in physics to avoid simplifications that may misrepresent the underlying concepts. Some participants emphasize that the traditional understanding of these forces may be too simplistic, while others defend its validity. Overall, the thread underscores the complexity of force interactions in different frames of reference.

Centripetal and centrifugal forces

What do you think about the following division, i.e. distinction between centripetal and centrifugal forces?

gravipetal-gravifugal
electropetal-electrofugal
magnetopetal-magnetofugal
nucleopetal-nucleofugal
cohesipetal-cohesifugal

Every known force can function as a centripetal force, and has inevitable reaction in centrifugal direction. The terms CENTRIFUGAL AND CENTRIPETAL are only denominations of direction of actioning - toward center or away of it.

E.G. Astronauts which are orbiting Earth are levitating due to gravifugal force. In a case of levitation of astronauts is erroneus to say: they are levitating due to "centrifugal force" because that term is to general, or to large.

Good idea, althought i don't really agree with it.
Scientists try their best to make science 'simpler', with fewer terms, etc ...
Now, in the case of an astraunot orbitting round earth, the gravitational force on the astraunot works as a centripetal force (for a person watching from an inertial frame of refference), so, the force that the astraunot feels as levitating force is actually a centrifgual force (remember he is not in an inertial frame of refference), so i don't see where the problem comes up.
You said :
a case of levitation of astronauts is erroneus to say: they are levitating due to "centrifugal force" because that term is to general, or to large.
Can you explain this more, why is it erroneous to say "They are lifted due to centrifugal force, that is due to a centripetal force which is the gravitational force" ?
 
"""a case of levitation of astronauts is erroneus to say: they are levitating due to "centrifugal force" because that term is to general, or to large."""

It is more correct and more precize and clearer to say "gravifugal force", because it is the reaction to the gravipetal force action.

If we rotate the little stone on the string, we also deal with centrifugal and centripetal force (speaking generaly), but it is much better to say: cohesipetal and cohesifugal or solidopetal and solidofugal force.

There are some esential differences between the two pair of force

Gravipetal - gravifugal
and
Cohesipetal - cohesifugal

Equation for the first pair - grav.:
GMm/R2 - mv2/R
Equation for the second pair - cohesi.:
mv2/r - mv2/r

Behaviour of the rotating mass and forces is also quite different.

No... you still misunderstand the idea of centripetal effects. What happens is best seen as falling but missing the ground. The object in orbit is continuously falling under the unbalanced force of attraction, but constantly missing the ground.

Have you done calculus?
 
Dear sir,
your opinion is not incorrect, but it is only simplicication for schoool-children.
 
That is why I asked if you know calculus. I can give you the full complex version if you desire.

And you didn't say why the model isn't correct.
 
OK, OK
You are right
 
But there is no centrifugal force...
 
I do not understand what are you talking about, but you are right.
