$A$ parabola

Vedclass · Answer

(C) The kinetic energy $(K.E.)$ of an object is defined by the formula $K.E. = \frac{1}{2}mv^2$,where $m$ is the mass and $v$ is the speed of the body.Since the mass $m$ is constant,the relationship between kinetic energy and speed is $K.E. \propto v^2$.This equation is of the form $y = kx^2$,which represents a parabola.Therefore,the graph plotted between speed $(v)$ on the $x$-axis and kinetic energy $(K.E.)$ on the $y$-axis is a parabola.
