Question
Which of the following graphs cannot possibly represent one dimensional motion of a particle

- I and II
- II and III
- II and IV
- All four
The correct answer is: All four
I is not possible because total distance covered by a particle increases with time
II is not possible because at a particular time, position cannot have two values
III is not possible because at a particular time, velocity cannot have two values
IV is not possible because speed can never be negative
