CBSE Class IX Science SA 2 (3 Marks)

Answer 1

(i) A body is in uniform acceleration if it travels in a straight path when its velocity increases or decreases by equal time intervals. (ii) A body is in non-uniform acceleration if it travels in a straight path when its velocity increase or decrease by unequal amount in equal time intervals. 

Answer 2

hey mate....

(i) Uniform acceleration: When a body travels with the same velocity in the given time, then the acceleration is said to be uniform.

(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.
