Question

Does the phrase direction of zero vector" have physical significance? Discuss it terms of velocity, force etc."

Answer 1

Answer:

Dear,

       As 0 vector don't have any magnitude and direction as this is considered as a null vector.So there is no meaning of discussion on that vector.And also it does not has any physical significance as it initiates and ends at same

place.

Explanation:

If you want more clear answer let us consider a 0 vector which has null value.

And                  velocity=displacement  /  time  ,

             and if there is no displacement( as i explained above  it initiates and ends at same place) then there is no velocity.

and if there is no velocity there is no accleration as

               Accleration= change in velocity / Time  ,

and if no accleration there is no force involved ,

as             Force=MA          where M=Mass,

                                                        A=Accleration.

I hope it helps.

Answer 2

Yes , the phrase direction of zero vector have physical significance.

Explanation:

• In physics, a zero vector has physical importance, as the zero vector’s operations provides us a vector.
• For the existence of vector algebra, the null vector’s existence is necessary.  
• For vector algebra, the null vector’s existence is required as the essential additive inverse it acts, there will be no null vector’s physical importance. In fact, it is an undeterminable direction.
• When a force of 0N is applied by the man, there is no force applied by him. So, there cannot be any possible force, but the direction has a physical significance.
