Difference between centrifugal force vs reactive centrifugal force?

In summary: In this case, the term "reactive centrifugal force" would be more accurate, as the force is reactive to the motion of the body.In summary, the difference between centrifugal force vs reactive centrifugal force is that centrifugal force is the force exerted by an object in a rotating reference frame while reactive centrifugal force is the force exerted by an object in a co-rotating frame. The interaction forces (also called “real forces”, but I prefer the term “interaction” as it is less philosophical and more descriptive) arise from interactions between objects. Importantly these interactions follow Newton’s

So on PF out of the term "reactive centrifugal force" the only non-annoying part is "force" :smile:

It's a momentum flow, darn it :-)

Edit: And may the Schwartz be with you always.

Haha! But Star Wars just wouldn't be the same if the Jedi had to say "Use the momentum transfer, Luke!"

I just watched Rogue One again, so I guess it would be "I am one with the momentum transfer, the momentum transfer is with me ..."

I was allways excelent at math but allways strugle with physics and find very harder to understand than math..
I don't know if I am stupid or I have poor bascis of physics so it is hard to follow you ,but I find most of people consider physics harder to learn...

A.T. ,Dale,jbbriss44,Ibix etc,,are you proffesors of phyiscs or normal people,how you know physics so well?

Purely amateur here. I do IP networking for a living. Though the team members have nick-named me "The Professor".

I teach physics and programming professionally, but as an instructor in industry rather than at a university in academia

It's a spare time thing for me as well, although I have done postdoctoral work in physics in the past.

Frames, switching between them, and keeping track of how representations change as you do so is non-trivial, I think. This confusion of terminology about centrifugal forces doesn't help.

Are you a proponent of the Karlsruhe Physics Course? This is however the worst product of physics didactics ever. It's maximizing the confusion of students and is in some parts conceptually wrong (applying the Gauß integral theorem to non-closed surfaces, selling entropy as the same as heat or as a modern form of phlogiston etc. etc.).

Well, if you are excellent at math, try theoretical physics!
