Explanation:
according to my understanding, the value of gravitational acceleration changes because;different planets have different gravitational pull.
for example you may ask yourself why is it that the gravitational acceleration is not the same on earth and the moon.
this is because the gravitational force acting on an object on earth is greater than the gravitational force acting on an object and the Moon .
You know the moon is located in the space and one can fly, stand,dance etc.
all because the gravitational acceleration is low.
as for me when the distance from the centre of the Earth increases,
the gravitational acceleration decreases.
A good example is given by the moon.
The moon is miles away from the Earth and its gravitational acceleration is quite low .hope you got me.
