Answer:

 Sol.) The total distance covered by Shyam

                                                        =AB+BC+CD+DE+EF

                                                        =(1+2+1+2+2)Km = 8 Km

        The magnitude of displacement of Shyam

                                                          = AF = 5 Km

        The magnitude of displacement is less than the distance covered by him.

Question 2. Asked on :31 May 2020:09:30:54 AM

 Give a short note on displacement?

-Added by Aman Senapati Physics » Motion

Answer:

  1. Displacement during a given time is the shortest distance measured from initial position of the object.
  2. Displacement is characterised by its magnitude as well as direction. Thus,displacement is a vector.
  3. Displacement can be positive or negative or even zero.

Question 3. Asked on :31 May 2020:09:26:44 AM

Give a short note on distance?

-Added by Aman Senapati Physics » Motion

Answer:

  1. Distance is the total path length covered by an object during a given time.
  2. Distance has a magnitude only and no direction.Thus,distance is a scalar.
  3. Distance is always taken positive.
