Hi,

It will be appreciated if someone can clarify this for me.

For rotation, one can fix the frame of reference on the rotating object by adding centrigual force and coriolis force. But, what is the difference between these two types of ration:

1.

|

|

|

--- + ---

|

|

|

2.

---

--- + ---

---

Here "+" is the center of rotation.

Thanks!

******o******

******o******

******o******

**ooo*+*ooo**

*************

******o******

******o******

******o******

case 2:

*****ooo*****

*************

**ooo*+*ooo**

*************

*****ooo*****

"*" indicates white space
