A body starts from rest and moves with uniform acceleration. Which graph accurately represents its motion?
A. A decreasing straight line on a velocity-time graph.
B. A straight line displacement-time graph passing through origin.
C. A straight horizontal line on a velocity-time graph.
D. A parabolic displacement-time graph curving upwards.
Answer: Option D
Solution (By JKSSB Mock Tests)
For uniform acceleration starting from rest, the displacement equation is s = ½at². Since displacement 's' is proportional to the square of time (t²), the displacement-time graph is a parabola curving upwards. A straight horizontal line on a v-t graph means constant velocity (zero acceleration).
