Question

when object falls freely to the ground , its acceleration is uniform. give scientific reason.

Answer 1

Hey!

___________________

Uniform acceleration - Acceleration in which velocity changes at equal intervals of times in equal amount.

When a body falls towards the ground, acceleration is uniform , body changes its velocity with time. At highest point velocity is 0 and as it falls down, it keeps on changing and when it falls on ground, final velocity is different. It changes at uniform rate.

Gravitational force is applied on the body and it doesn't depend on mass of the body, 'g' is constant. In other words, when a body falls on the ground under free fall, it's velocity increases at rate of 9.8 m/s^2. (value of 'g').

Hope it helps...!!!

Answer 2

A force is required to change the speed and direction of respective object.This is known as acceleration.It depends on the size (magnitude)of an object and made of an object....THAÑKYOU!!!!!
