Question

I m in 9th class my ques.
F=mv^2/r
From where did it come?????

Answer 1

Answer:force is m*a and a is v/t.

So u have F=(m*v)/t. using time(t) as (r/v) u have ur formula .just chill boy u will learn it in afterlife .

Answer 2

Answer:

F = (mv^2)/r

Explanation:

it is centripetal force in circular motion.

it is the force which acts on body towards centre

F=ma

here a is centripetal acceleration

centripetal acceleration = v^2/r

F = m×a

F = (mv^2)/r
