Is Centripetal Acceleration Constant in Uniform Circular Motion?

[Qwertywerty]

You mean a constant velocity.

No , sorry , that's not what I meant . See my edited post .

Edit : If an object's velocity is changing in the sense that it's direction changes but not it's magnitude , then force is not affecting the speed of the object - because magnitude of velocity isn't changing in that case , only it's direction is .

yes that's true but in places like planetary motion
here in the string example there is gravitation of Earth and to balance it u need a constantly applied force
thats what i am talking about

Suppose the object is kept on a table . Then , in that case , normal cancels gravitational force .
If it is a vertical circular motion , analysis is not so simple .

here in the string example there is gravitation of Earth and to balance it u need a constantly applied force
thats what i am talking about

I'm sorry , is this what you have been talking about this whole time ?

maybe u still don't understand my question

 

[Qwertywerty]

Okay , could you please repeat your question ? Also state exactly what kind of circular motion the object is doing .

 

[faiziqb12]

my question is
a body is in a uniform circular motion on Earth
it means that we balanced all the unbalanced forces acting on it to create a uniform velocity
so how much is the force we applied to balance the forces?

actually i went to the end of the doubt that i have
please address the last part of it here

On the surface , or in the air ? You mean , uniform speed ?
Also , it's to a string and the only other force is the force of gravity ?

its in the air
and you i meant uniform speed
i never said there's only these two forces

leave it i understood all of it
now i just need this part of the question be answered
