JEE Main Physics question

Look at the graphs (a) to (d) carefully and indicate which of these possibly represents one dimensional motion of a particle [K CET 2006]

(A)A closed circular loop in the – plane
(B)An S-shaped, single-valued, monotonically increasing curveCorrect
(C)A "speed" vs time curve oscillating symmetrically above and below the time axis
(D)A self-intersecting spiral/loop curve

Answer: (B)

Solution

Genuine 1-D motion requires a single-valued relationship at every instant; closed loops, self-intersecting
