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').

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!!!!!

ritu2822003: hey you !!!! it dosent depend upon size

Nikki57: Exactly, Dear, it doesn't depend on size

Vejìng744: HEÝ friend accleration depends on size that is magnitude and mass of object!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Nikki57: A ball and a stone will fall at same time, no matter whats the size

Nikki57: Umm..

Nikki57: Then buoyancy comes in between, if mass is more upthrust by air will be less

Vejìng744: OKAÝ I'm not talking about uniform accela....I'm talking about acceleration!!!!!!''!!!!!!!!!!

Nikki57: Question is something else

Vejìng744: oķaý

ritu2822003: got it dear
