Surfing For Physics Formulas For Distance?

Donna asks…physics distance, acceleration, and velocity graphs help?say i'm given a position vs time graph, and i have to convert it to acceleration vs time as well as velocity vs time, how do i do this?

is there a formula?

my points are:
at 1 second, position = 31 cm
at 2 seconds, position = 42 cm
at 3 seconds, position = 42.5 cm
at 4 seconds, position = 43 cm
at 5 seconds, position = 42.4 cm

so i know that the slope is different for each second, but how exactly do i change this d vs t
