How do i get an idea, or a 'feel' of the components of the acceleration in polar coordinates which constitute the component in the eθ direction?
from what i know, a= (r¨−rθ˙^2) er + (rθ¨+ 2r˙θ˙) eθ ;
(where er and eθ are unit vectors in the radial direction and the direction of increase of the polar angle, θ.)
The two components in er direction--- r¨ and rθ˙^2 are the usual acceleration along radius vector and the centrifugal force experienced. But what is the significance of the other two terms?. Is there any day-to-day or a common situation where we experience the Coriolis force and the other term?
I can memorize the formula and use it, but i will truly 'understand' its significance only if i can 'feel' the terms..
Thanks!
