    If the figure below represents a parabola, identify the physical quantities representing Y and X for constant acceleration.

    A)  \[X=\] time, \[Y=\] velocity

    B)  \[X=\] velocity, \[Y=\] time

    C)  \[X=\] time, \[Y=\] displacement

    D)  \[X=\] time, \[Y=\] acceleration

    Correct Answer: C

    Solution :

    As displacement \[s=ut+\frac{1}{2}\,\,a{{t}^{2}}\] i.e. parabola and velocity v = u + at i.e. straight line where, t = time since, body is in uniform acceleration so, velocity of particle is increasing with time. Hence, this is displacement time graph with X as time axis and Y as displacement axis.
