Question
An object starts from rest and moves with uniform acceleration. The displacement of the object is proportional to ___ of time.
Answer: Option C
:
C
Let 'u' be the initial velocity, 't' be the time taken, 's' be the displacement and 'a' be the acceleration.
From second equation of motion, we know, s=ut+12at2
Since the object starts from rest, u = 0
Therefore, s=12at2
The motion is uniform accelerated motion. Therefore 'a' is constant.
⇒s∝t2
