Why null vector has a direction as it has magnitude 0?
The null vector is a special case where both magnitude and direction are undefined. This vector represents a point in space, rather than a physical quantity with magnitude and direction.
What is meant by negative vector?
A negative vector is a vector that has the opposite direction of the original vector but the same magnitude. It is obtained by multiplying the original vector by -1. In other words, if the original vector points in a certain direction, the negative vector points in the exact opposite direction.
Which motion does the vector show?
The vector shows the direction and magnitude of motion of an object. The direction is represented by the direction of the vector arrow, and the magnitude is represented by the length of the vector.
A vector is a quantity with magnitude and ___?
A vector is described by magnitude and direction (a scalar has only magnitude).
What two vectors does a vector have?
It has both velocity and direction. A vector has direction and magnitude.
What is null vector?
NULL VECTOR::::null vector is avector of zero magnitude and arbitrary direction the sum of a vector and its negative vector is a null vector...
How do you add two null vectors by following vector laws of addition?
The sum of two null vectors is a null vector. And since a direction is not relevant for a null vector, the resultant has no direction either.
Can you add zero in null vector?
no,zero cannot be added to a null vector because zero is scalar but null vector is a vector,although null vector has zero magnitude but it has direction due to which it is called a vector.
What is different between negative vector and null vector?
A null vector has no magnitude, a negative vector does have a magnitude but it is in the direction opposite to that of the reference vector.
Why null vector has a direction as it has magnitude 0?
The null vector is a special case where both magnitude and direction are undefined. This vector represents a point in space, rather than a physical quantity with magnitude and direction.
What is the direction of null vector?
There are two possible answers to this; a) It has no direction b) It points in all directions Answer a is really more true, as the notion of a null vector precludes any notion of a direction, but the correct answer is b.
What is the direction of the resulting vector if vector of 2 units North is added to a vector of 2 units South?

Can a null vector be added to zero?
No, a vector cannot be added to a scalar. You could multiply a null vector by zero (and you'd get the null vector), but you can't add them.
Can you add 0 to null vector?
Yes, you can add anything to null vector.
What is the difference between zero and zero vector in vector algebra?
Zero is a number (a scalar quantity without unit) while zero vector (or null vector) is a vector quantity having zero magnitude and arbitrary direction.
Can you add 0 to a null vector?
Yes, any number can be added to a null vector.
What is the result of multiplying vector components by a scalar?
If the scalar is > 1 the resultant vector will be larger and in the same direction. = 1 the resultant vector will be the same as the original vector. between 0 and 1 the resultant vector will be smaller and in the same direction. = 0 the resultant vector will be null. If the scalar is less than 0, then the pattern will be the same as above except that the direction of the resultant will be reversed.
