Question

Identify the correct relation.

$K E \propto v^{2}$
$K E \propto \frac{1}{v^{2}}$
$K E \propto 2 v$
$K E \propto \frac{v}{2}$

hint Hint:

KE is directly proportional to v²

The correct answer is: $K E proportional to v squared$

We know that kinetic energy is given by -KE=1/2 mv². In this formula mass is constant of a body so KE is directly proportional to v².
