A Free-fall motion is a special case of uniformly accelerates motion wherein gravity is only force acting on an object. It has the following assumptions :
-motion is along the vertical
-velocity is either upward or downward
-weight is the only the fprcw acting on object
-acceleration is always g= 9.8m/s squared
(depends if the measurement used is in feet or centimeters. In which case, g= 980 cm/s squared for centimeters and g=32.2 ft/s squared for feet)
