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 a magnitude of a vector has negative value?
You express a vector along the X-axis as a negative vector when the arrow representing the vector would point toward negative x.
momentum is a vector quantity and therefore has direction. all vector quantities can have negative direction
No, vector, besides a value, has also a direction.
270 degrees
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 a magnitude of a vector has negative value?
You express a vector along the X-axis as a negative vector when the arrow representing the vector would point toward negative x.
a vector with nothing in it
No because magnitude is like length and you cannot have negative length
When the arrow representing the vector would point toward negative x.
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...
momentum is a vector quantity and therefore has direction. all vector quantities can have negative direction
No, the value can't be negative because magnitude of a vector is just how long it is regardless of its direction. :-)
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.
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.
A resultant vector is one vector which can replace all the other vectors and produce the same effect.
