Question

when an object Falls freely to the ground its acceleration is uniform give reason

Answer 1

because when an object is falling freely then in every 1 second its acceleration increases to 9.8 m/s^2 or 10 m/s^2 and that object will cover same distance in every 1 second.

hope you understand.

Answer 2

when an objects falls freely its acceleration is constant because in a free fall the acceleration does not depends on the mass of body . the uniform acceleration is produced due to gravitational force . in other words when a body falls freely to the ground under the action of gravity . its velocity increases at the constant rate of 9.8m/s2.
