Question

give scientific reasons when the body falls freely to the ground its motion as the uniform acceleration​

Answer 1

When an object fall freely on the ground, it is under the effect of a constant force known as force of gravity. No other forces at on it. Hence, from Newton’s second law of motion, e can say that the constant force of gravity accelerates the freely falling object informally. This uniform acceleration is known as acceleration due to gravity which acts towards the centre and is denoted by g.

Answer 2

When an object falls freely to the ground, its acceleration is uniform. Hint: When an object falls freely on the ground, the force of the gravity works on it. So the acceleration on the object is the acceleration due to gravity. So the acceleration is uniform on the freely falling body.
