The components of a vector or what?
The components of a vector are magnitude and direction.
What is a magnetic field vector?
It is a way of representing the magnetic force at a point in the field. The magnitude and direction of the vector represents the strength and the direction of the magnetic force acting on a charged particle in the field.
How does the magnitude of a vector relate to the dot product?
The magnitude of dot product of two vectors is equal to the product of first vector to the component of second vector in the direction of first. for ex.- A.B=ABcos@
Cross product is not difine in two space why?
When performing the cross product of two vectors (vector A and vector B), one of the properites of the resultant vector C is that it is perpendicular to both vectors A & B. In two dimensional space, this is not possible, because the resultant vector will be perpendicular to the plane that A & B reside in. Using the (i,j,k) unit vector notation, you could add a 0*k to each vector when doing the cross product, and the resultant vector will have zeros for the i & jcomponents, and only have k components.Two vectors define a plane, and their cross product is always a vector along the normal to that plane, so the three vectors cannot lie in a 2D space which is a plane.
When is the vector sum not equal in magnitude to the algebraic sum?
The magnitude of the vector sum will only equal the magnitude of algebraic sum, when the vectors are pointing in the same direction.
How do the magnitudes and direction pair?
Magnitude and direction are related in vector quantities. The magnitude represents the size of the vector, while the direction indicates the orientation of the vector in space. In a 2D plane, direction can be specified by an angle relative to a reference axis, while in 3D space, direction can be defined by using angles or unit vectors along the coordinate axes.
Scalar and vector?
A scalar is a magnitude that doesn't specify a direction. A vector is a magnitude where the direction is important and is specified.
Is velocity a vector?
True ,velocity is a vector quantity ,it is specified by a magnitude and direction.
If a vector has constant direction then?
There is almost never an "IF". All non-zero vectors have a constant, specified direction. Only a zero-vector has a direction which is unspecified.
What is a quantity that is specified by size and direction?
. Velocity Acceleration
What is speed in specified direction called?
Speed in a specified direction is referred to as velocity. Velocity is a vector quantity that includes information about both the speed and direction of an object's motion.
Do vectors have direction?
Yes, vectors must have the direction. Without direction, it is simply a scalar quantity.
Is the position scalar or vector quantity?
Position is a vector quantity as it has both magnitude (distance) and direction in space.
What has size and direction?
A vector has size (magnitude) and direction. It represents a quantity with both a numerical value (magnitude) and an associated direction in space.
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.
What is the Velocity of speed?
Velocity is the vector form of speed. It is the speed of an object in a specified direction.
Does the phrase direction of zero vector have physical significance?
No, the zero vector has no direction as it does not have magnitude or point in any specific direction. It represents a point in space with no displacement.
