ok let me try again. if i am sitting on a table and pulling a string at the end of which is a ball. now another person sitting next to me will see that the radial acceleration is towards me wrt him right ? so in this case the radial acceleration doesn't change?

also what if we pull the string with the object towards ourselves. isn't that only one direction? and the radial acceleration is also towards us? is this correct also?

yes i meant that only. thanks a lot.

lol yes i have and the radial acceleration changes wrt the ground and not wrt me like my earlier example.so are all these examples discussed in this thread correct?

if the string is at rest and nothing is moving then there is no radial acceleration but that is a stupid answer according to me. what if we pull the string with the object towards ourselves. isn't that only one direction? and the radial acceleration is also towards us?

please give me another hint. isn't the example i gave you about the butterfly...correct? relative to the butterfly the direction of radial acceleration doesn't change

Thanks for the hint. is it when i revolve a ball attached to a string round and round in 1-d by spining the string? also can this be possible when i rotate a ball in 2-d attached to a string and supposing a butterfly is facing the object which rotates always so that there is no relative...

no there is only one question -a ball is tied to a string and rotated.the following statement is true or false- Direction of radial acceleration MAY remain the same? yes it may ask me to do that but according to you is this ever possible? because the question says it "may" be possible. this...

Naming the book won't help. it is in the form of a question which says- a ball is tied to a string and rotated.the following statement is true of false- Direction of radial acceleration MAY remain the same? And according to the book it is true.

how does this article answer my question ?? please give me a case where radial acceleration doesn't change direction @rcgldr

I have a big confusion. There is a question in my book which basically says that a ball is tied to a string and rotated. and it asks me to tell whether the following statement is true of false. Direction of radial acceleration MAY remain the same. This statement is true. Please explain to me a...
