are centripetal and centrifugal forces considered to be action-reaction forces?
consider a mass m tied to a string centripetal force is provided by the string on to the mass m while centrifugal force acts on string by the mass m
drwing a free body diagram of the mass m i can say the forces acting on it are:
tension pulling it inwards
but actually as the mass m is attached to the string,wont the centrifugal force given by the mass on the string also affect it?(that is act on it?)
as mass m and string are joined to each other?

yes. you are right. these are action and reaction forces.
you are also right that centrifugal force also affects on the mass.
whenever a circular motion is come for discussion then centripetal and centrifugal also comes. then other conditions are applicable but those forces first.

|dw:1332864882062:dw|then there shud be net acc outside the circle creating circling of mass imposible!
if mass is whrilling in the circular motion, it is due to centripetal force.
then u agree that centrifugal acts on the string by mass m?
since they are connected,it will indirectly affect mass m also?
so why is dat when we solve sums we draw free body diagrams showing only T,mg and the caused radial mv^2/r
when an equal centrifugal force acts radially outwards nullyfing the entire effect and
then if there is no pulling force(as centripetal force has been nullified) then how does it go around the circle?===no pulling inside as per my theorey!
cause tension is also a force.
Tension is the force which comes when a body is tied with a string either the body is moving in a circle or it is hanged or any case like this.
centripetal force is the force which comes when a body only rotates around a fixed point(axis).
So in circular motion centripetal force is equal to tension. coz the body is tied to the string.
also. both forces equal therefore a body keeps round and round and round in the circle. if any of the force increases then case would go different way for example, if centrifugal force increases then string will break up and object will go far (no more remain in circular motion)
sorry shyaan i figured out the answer
sry for confusing u
the centrifugal force actually is by the string on the point of attachment
:)thank u for ur response!
centrifugal is by string on the centre of rotation(source point)
centripetal is by string on mass m
centrifugal force is then tension ... to ward the center
centripetal force is by the mass (not by the string) ... acts outward.
the body moves in circular motion because along the circular path, these two forces are equal along the path of circle
centrifugal is by string on the centre of rotation(source point) centripetal is by string on mass m
you are right
do you know that is tension?
if i pull a string ... where is the tension directed?
opposite side of the pull.
looks like i made mistake above ... i would like to interchange centripetal and centrifugal
yes. you did.
centrifugal force is not a real force.. and thus is not an action or reaction.
The action and reaction are - The string is pulling the mass (centrepetal force on the mass)
The mass is pulling the string by its inertia (tension in the string)
Altough using the concept of centrifugal force is convinient it is not a real force but an outcone of the inertia of the body
or_dobkowski is corect.
centrifugal is only "real" to you if you are on board the moving body.|dw:1333181616890:dw|
yeah centrifugal is the centre-fleeing force
with acts on the source that provides centre-pulling centripetal force on the body
for example when a body is tied to a string,
centripetal force is given by the string on to the body
and centrifugal force acts on the string straightening it out(in the outward direction)
