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.
Can the magnitude of a vector have a negative vector?
No because magnitude is like length and you cannot have negative length
When should you express a vector along the x axis as a negative vector?
When the arrow representing the vector would point toward negative x.
Can the magnitude of a vector be negative?
No, the value can't be negative because magnitude of a vector is just how long it is regardless of its direction. :-)
Can the magnitude of a vector have a negative value?
The magnitude of a vector is always treated as non negative and the minus sign indicates the reversal of that vector through an angle of 180 degree.

Can the magnitude of a vector has negative value?
can a magnitude of a vector has negative value?
When should you express a vector along the x-axis as a negative vector?
You express a vector along the X-axis as a negative vector when the arrow representing the vector would point toward negative x.
What is meant by negative vector?
It is a vector that has the opposite direction to the reference positive direction. (A vector is one point in space relative to another.) Negative vector is the opposite direction
Can the magnitude of a vector have a negative vector?
No because magnitude is like length and you cannot have negative length
When should you express a vector along the x axis as a negative vector?
When the arrow representing the vector would point toward negative x.
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 can an object have negative momentum?
momentum is a vector quantity and therefore has direction. all vector quantities can have negative direction
Can the magnitude of a vector be negative?
No, the value can't be negative because magnitude of a vector is just how long it is regardless of its direction. :-)
Can the magnitude of a vector have a negative value?
The magnitude of a vector is always treated as non negative and the minus sign indicates the reversal of that vector through an angle of 180 degree.
What decscribes a vector?
A vector is a quantity described by size and direction. Mathematically, the square of a vector is negative, e.g. i^2 = -1, thus a quantity whose square is negative is a vector, e.g. 5i is a vector because (5i)^2 = -25.
Can scalar be a negative number?
Yes, a scalar can be a negative number. For instance: c<x₁,x₂> = <cx₁,cx₂> such that <x₁,x₂> is a vector. Let c = -1 for instance. Then, we have this vector: <-x₁,-x₂> Compared to <x₁,x₂>, <-x₁,-x₂> has negative signs. In physics and mathematics, if we multiply the vector or something by a negative value scalar, then the direction of the vector is reversed, and the magnitude stays the same. If the magnitude increases/decreases, and the direction of the vector is reversed, then we can multiply the vector by any negative non-1 scalar value.
