Q. For a body moving with uniform acceleration along straight line, the variation of its velocity $(v)$ with position $(x)$ is best represented by
Motion in a Straight Line
Solution:
For uniform acceleration, $a \rightarrow$ constant
$v^{2}=u^{2}+2 a s$
$\Rightarrow v^{2} u x (\because u=\text { rest })$
