Question

Which of the following graphs can not possibly represent one dimensional motion of a particle

  1. I and II  
  2. II and III  
  3. II and IV  
  4. 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
