Question

diffrance between  uniform and non unifrom accceleration  

Answer 1

Non-uniform Acceleration refers to change in velocity of a body is different or non-uniform in equal intervals of time, then the body will posses Non-Uniform Acceleration.
Whereas, in Uniform Acceleration the change in velocity is increasing or decreasing at a constant rate or is increasing or decreasing uniformly in equal intervals of time, then the body will posses Unifrom Acceleration. 

Answer 2

accelaration means rate of change of velocity.A body is said to be in uniform accelaration if it moves with equal velocity in equal intervals of time. Abody is said to be in non uniform accelaration if it covers unequal velocity in equal intervals of time or equal velocity in unequal intervals of time
