Vector, in physics, a
quantity
that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity's magnitude. Although a vector has magnitude and direction, it does not have position.
Is a vector magnitude and direction?
A vector is defined by its magnitude, or the length of the line, and its direction, indicated by an arrowhead at the terminal point. Thus, a vector is
a directed line segment
.
When two vectors have the same magnitude and direction is called?
If two vectors have the same magnitude (size) and the same direction, then we call them
equal to each other
.
Can a physical quantity having both magnitude and direction be a vector?
Vector, in physics, a quantity that has both magnitude and direction. For example, displacement, velocity, and acceleration are vector quantities, while speed (the magnitude of velocity), time, and mass are scalars. …
What does a zero vector mean?
: a vector which is
of zero length and all of whose components are zero
.
What is vector and give any two examples?
A vector is a quantity or phenomenon that has two independent properties: magnitude and direction. The term also denotes the mathematical or geometrical representation of such a quantity. Examples of vectors in nature are
velocity, momentum, force, electromagnetic fields, and weight
.
What is an example of vector quantity?
Vector, in physics, a quantity that has both magnitude and direction. … For example,
displacement, velocity, and acceleration
are vector quantities, while speed (the magnitude of velocity), time, and mass are scalars.
Which is not a vector quality?
Answer:
Speed
is not a vector quantity. It has only magnitude and no direction and hence it is a scalar quantity.
Does speed has both magnitude and direction?
Speed is a scalar quantity which is fully expressed by magnitude alone. Velocity is a vector quantity which
is expressed by both magnitude and direction
. Suppose that you are driving your car at 55 mi/hr along a road while heading east.
What is null vector example?
A null vector is a vector that has magnitude equal to zero and is directionless. It is the resultant of two or more equal vectors that are acting opposite to each other. A most common example of null vector is
pulling a rope from both the end with equal forces at opposite direction
.
Can a basis include the zero vector?
Indeed,
the zero-vector cannot be a basis because it is not independent
. Taylor and Lay define (Hamel) bases only for vector spaces with “some nonzero elements”.
Is a zero vector linearly independent?
In the theory of vector spaces, a set of vectors is said to be linearly dependent if there is a nontrivial linear combination of the vectors that equals the zero vector. If no such linear combination exists, then the vectors are said to be
linearly independent
.
What is an example of a biological vector?
Vectors are frequently arthropods, such as
mosquitoes, ticks, flies, fleas and lice
. Vectors can transmit infectious diseases either actively or passively: Biological vectors, such as mosquitoes and ticks may carry pathogens that can multiply within their bodies and be delivered to new hosts, usually by biting.
How many types of vectors are there?
The
four
major types of vectors are plasmids, viral vectors, cosmids, and artificial chromosomes. Of these, the most commonly used vectors are plasmids.
Which of following is a vector quantity?
Vector quantity has
both magnitude & direction
. For example distance, speed, time, temperature , work, energy, charge, voltage are all scalar quantities. Displacement, velocity, acceleration, force, electromagnetic field are all vector quantities.
