(A) Potential energy of a simple pendulum (y axis) as a function of displacement (x axis).

(B) Displacement (y axis) as a function of time (x axis) for a one dimensional motion at zero or constant acceleration when the body is moving along the positive x-direction.

(C) Range of a projectile (y axis) as a function of its velocity (x axis) when projected at a fixed angle.

(D) The square of the time period (y axis) of a simple pendulum as a function of its length (x-axis).
