Answer:

The graph indicates free fall of a body from a height under constant acceleration due to gravity hitting ground after elapse of some time.

Explanation:

The graph depicts how does a quantity #A# changes with the change of another quantity #B#
Following observations are made:

  1. The graph is quite similar to a parabola.
  2. Quantity #B# decreases with increase in #A#.
  3. The decrease in #B# is not constant. It changes with increase of #A#.
  4. Initially the decrease is small. With increase of #A# the decrease increases.
  5. At a point when #B=0#, value of #A# is maximum.
  6. At a point when #B# is maximum, value of #A=0#.

If we recall kinematic equations, we can easily identify the graph as drawn between height #h# and time #t# of a free falling body under gravity #g#, dropped from height #h# with initial velocity equal to zero.
The equation is
#h=-1/2g t^2#
where height #h# is the quantity #A# and time #t# plotted as quantity #B#

The graph indicates free fall of a body from a height under constant acceleration due to gravity hitting ground after elapse of some time.
