Question

Why does earth impart same acceleration to all bodies? Is it possible to have negative value in speed & displacement?​

Answer 1

Acceleration depends only on the Mass of Earth and Radius of Earth at any point on the surface of Earth.

            g = G M / R^2

Since  Radius is nearly same all around the Earth, g is nearly same.  Still there is a little variation from the Equator to the pole.

hope this helps u.☺️❣️
