Physics Motion in a Straight Line Mix MCQ (Single Correct)

For one dimensional motion if

v av = average speed = average velocity

v inst = instantaneous speed

= instantaneous velocity; v = speed

Then match the following

Column-I	Column-II
(i) =	[A] for uniform motion in any direction
(ii) = v	[B] for uniform motion in given direction
(iii) vinst = vav	[C] Always true
(iv) < v	[D] Never true

The correct answer is:

CHECK THE SOLUTION

Ans.

(i) [B]

(ii) [C]

(iii) [A, B]

(iv) [D]

Sol. (i) for uniform motion in given direction

(ii) Always true

(iii) for uniform motion in any direction, for uniform motion in given direction

(iv) Never true
