Question 1

When will you say a body is in

(i) uniform acceleration? (ii) non-uniform acceleration?


(i) Uniform acceleration : A body is said to be in uniform acceleration when its velocity is changing at the same rate i.e when its acceleration in unit time is the same. 

example : An object in freefall is in uniform acceleration.

(ii) Non-uniform acceleration : When a body moves with unequal velocity in the equal interval of time, the body is said to be moving with non-uniform acceleration.

example : If a car covers 10 meters in the first two seconds and 15 meters in the next two seconds.
