[quote author=great.david]supported ......but i think centripetal force is mv^2/r and centrifugal acts in opposite direction to it which makes it -mv^2/r .......hope i'm on point[/quote]yea. Dat means am correct. Centrifugal force is -mv^2/r

[quote author=taiocol][/quote]pls y did u cancel d centrifugal. Wots d right answer pls?

taiocol: passengers standing in a bus ar thrown outward wen it takes a suden turn. Why does that happen.

it happens becos of d force dat pulls d passenger out of d bus. D force is called centrifugal force. D formula is -mv^2/r. (I stand 2 b corrected tnx)
