The falling of a body( or object) from a height towards the Earth under the gravitational force of earth (with no other forces acting on it) is called free fall.
We know Weight is also a force.
F=mg
Therefore, W=mg
F=Gm1m2/r2=
mg= GmM/ek
Cancelling out m from both sides we get
g= GM/de
Hence derived.
