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 has negative value?

No, the magnitude of a vector is always a positive value or zero. It represents the length of the vector and is a scalar quantity. Negative values are not associated with the magnitude of a vector.


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.


When should you express a vector along the x-axis as a negative vector?

You should express a vector along the x-axis as negative when it points in the negative x-direction relative to a chosen positive direction. This convention helps maintain consistency with vector addition and trigonometric methods.


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...


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.


What is negative vector in physics?

In physics, a negative vector is a vector that points in the opposite direction to a positive vector of the same magnitude. Negative vectors are used to represent quantities or forces that act in the opposite direction within a specific coordinate system.
