Gravity's effect on a ball dropped from a stop can be described by h(t) = -16t2, with h the height in feet and t the time in seconds.
After 1 second, the ball will have dropped 16 feet. After 2 seconds, the ball will have dropped 64 feet, and so on.
So, a graph could have t on the horizontal axis and h(t) on the vertical axis. Then the line would curve downward starting from (0, 0), with points on the graph (1, -16), (2, -64), and so on.
Note this doesn't account for horizontal velocity, only vertical velocity due to gravity.
