Q. Look at the graph (a) to (d) carefully and indicate which of these possibly represents one dimensional motion of a particle?
A) [image:3_image54.emf]
B) [image:3_image55.emf]
C) [image:3_image56.emf]
D) [image:3_image57.emf]
Explanation
(b) In figure (b), the particle is slowly accelerated first and reaches a constant velocity for the straight line portion. Then velocity decreases are finally it stops when it reaches the top straight line portion.
Hence, figure (b) represents one dimensional motion of a particle.
