The equation of distance as a function of time for a freely falling object is described, according to theory, by the equation:

since (vi=0 , yi=0)

y(t)= yi+vt*t+1/2*g*t2

 

Use the table for :

  • make a plot of y(t) vs t2  , and then calculate the slope in order to find g (the acceleration due to gravity, which is  9.8 m/s2)
  •  find Slope =  Δy / Δt2
  • g =
