Show a displacement-time graph for a free falling body.

Dear Student,
In case of free-falling body, its initial velocity, u = 0.
The body falls down with a constant acceleration, g = 9.8 ms^-2.
The displacement of the body as a function of time can be expressed as:
$$\begin{gathered} x=ut+\frac{1}{2}g{t}^2 \\ x=\frac{1}{2}g{t}^2 \end{gathered}$$

Displacement increases as a square function of time
The displacement-times graph of a free falling body is as follows:
