draw displacement graph for a freely falling body
considering your question to be about the displacement- time graph for free falling body; here is the answer;
freely falling body, initial velocity =u = 0, accleration=a= gravitational accleration= 9.8m/s²
We know the graph will be similar to
y = ax² , which is a parabola.
You can draw it by substituting the value of t at different times (t=1,2,3,4 etc)and finding the displacement at the time.
