Question

Figures i and ii below show the displacement-time graphs of two particles moving along xaxis we can say that

Answer 1

From equation of 2nd law of motion for uniform acceleration, we get X=Xo + 1 upon 2 at2

Thus,when acceleration or retardation is uniform, displacement time graph will be a parabola. In fig. (i) The particle is accelerated uniformly and in fig.

(ii) the particle is decelerated uniformly.
