Answer:
When an object falls freely to the ground, is the acceleration uniform? The acceleration of freely fall body is due to gravity, so our Earth's gravity has a costant magnitude |ā| = g = 9.8 m/s. So, yeah it is uniform.

Practically its acceleration is not uniform. In theory of secondary level physics we neglect upthrust caused by air,but practically it can’t be neglected,practically its acceleration is not just ‘g’,rather at each instant of falling there is fluctuation in acceleration. Gravitational force due to earth is not the only force acting on the body,rather the dragging force due to air is also there.If the force is not the same throughout the motion,then acceleration can’t ever be uniform while falling.
