Question

A particle starts from origin O from rest and moves with a uniform acceleration along the positive x-axis. Identify all figures that correctly represent the motion qualitatively. (a = acceleration, v = velocity, x = displacement, t = time) (A) a vs t: constant positive horizontal line (B) v vs t: straight line increasing from origin (C) x vs t: curve rising and then flattening (concave down) (D) x vs t: curve rising with increasing slope (concave up)

Accepted Answer

(A). The correct option (A) indicates that acceleration is constant, which is consistent with uniform acceleration. This means the acceleration vs time graph is a horizontal line, reflecting that the acceleration does not change over time.
