Question

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

Answer 1

If we consider a freely falling body from a greater height , there is a concept of bouyancy which is to be considered .

Bouyancy force is an upward force acted on a body which is submerged in a fluid .

Here the fluid is air .

Due to bouyancy force, the freely falling body doesn't under constant acceleration . Instead it will decrease gradually and the body will reach a maximum velocity called TERMINAL VELOCITY . After which the velocity will remain constant and acceleration remains zero

Answer 2

Heya user !!!

Here's the answer you are looking for

when an object falls freely to the ground its acceleration is uniform

REASON:

When an object falls freely , the only force acting on it is gravitational force. Since no other force acts on it, the acceleration of the object depends only upon the gravitational force.
As the acceleration due to gravitational force is constant, the acceleration is said to be uniform.
