Answer:
In Newtonian physics: free fall is any motion of a body where gravity is the only force acting upon it.
in this case V= u -gt. and S =ut +1/2 gt^2
all other forces like air resistance, buoyancy etc are Absent! it's an ideal case.
a Paratrooper whose Parachute did not open Yet , experience nearly a Freefall. Newtons Apple fell free and must have hit Newton on head with Velocity nearly 3.6 m/sec if the height from which it fell was 2 meters.
In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it.
