The motion of falling objects played a significant role in the history of science. An object which falls only due to the influence of a constant gravitational force is said to undergo free-fall motion. This motion will be examined in order to determine the acceleration due to gravity ( g ) . THEORETICAL BACKGROUND An object that is falling freely is acted upon only by a constant gravitational force exerted by the earth, and this force is directed towards the center of the earth. This constant gravitational force produces a constant acceleration due to gravity ( g ) . Acceleration is defined as rate of change of velocity with respect to time. That is: a = v v 0 t or v ( t )= v 0 + at (1) where a = acceleration of the object, v 0 = initial velocity, v = final velocity, t = time interval From equation (1), a plot of v vs. t
