x = v = speed (instantaneous)
y = KE = 1/2 m v² = (m/2) x² instantaneous kinetic energy => x² = 2/m y
This is in the form of x² = (4a) y which is the standard equation for a parabola with y axis as the axis of the parabola and (0,0) being the vertex of the parabola. The directrix is given by y = - a = - 1/(2m)
