Define: Acceleration due to gravity and derive mathematically.

Answer»

Solution :The GRAVITATIONAL force due to the EARTH on an object results in its acceleration. It is called acceleration due to GRAVITY.
We know
`F=(GMm)/(R^(2))`…………I
`F=mg` ………ii
From I and ii
`mg=(GMm)/(R^(2))`
For Earth `=g=9.77m//s^(2)`
