A vector is an ordered group of numbers. It has some integer size n, that is to say it has n numbers in it. Often it is writen with the arrow brackets like so v=<v1, v2, v3 ... , vn>
Because vectors are ordered <2,1> is different from <1,2>. An easy way to see this is to think that you are grocery shopping and the vector tells you how much apples you have as it's first component v1 and telling how much Oranges you have in the v2 component. It is clear that 2 apples and 1 orange is different from 1 apple and 2 oranges.

a vector
Physical meaning of vector?
A quantity involving direction and magnitude is called physically vector A quantity involving direction and magnitude is called physically vector

What is the physical significance of null vectors?
Zero vector or null vector is a vector which has zero magnitude and an arbitrary direction. It is represented by . If a vector is multiplied by zero, the result is a zero vector. It is important to note that we cannot take the above result to be a number, the result has to be a vector and here lies the importance of the zero or null vector. The physical meaning of can be understood from the following examples. The position vector of the origin of the coordinate axes is a zero vector. The displacement of a stationary particle from time t to time tl is zero. The displacement of a ball thrown up and received back by the thrower is a zero vector. The velocity vector of a stationary body is a zero vector. The acceleration vector of a body in uniform motion is a zero vector. When a zero vector is added to another vector , the result is the vector only. Similarly, when a zero vector is subtracted from a vector , the result is the vector . When a zero vector is multiplied by a non-zero scalar, the result is a zero vector.
Speed is to scalar quantity whereas velocity is to?
... a vector quantity. Speed is a scalar, meaning only the magnitude (a number) is used. If the direction of a movement is of interest, you use the word "velocity", instead, to describe the vector. A vector has both a magnitude and a direction.
Which of the following values could possibly be vector magnitudes meaning that combined with a direction they could become vector quanities?
6 miles5 meters30 kilometers/hourappexx30 kilometers/hour5 meters6 miles
What is the meaning of scalar?
In the quaternion analysis, a quantity that has magnitude, but not direction; -- distinguished from a vector, which has both magnitude and direction.
Can a vector be represented in terms of unit vector?
Yes, a vector can be represented in terms of a unit vector which is in the same direction as the vector. it will be the unit vector in the direction of the vector times the magnitude of the vector.
Is torque independent of location of axis?
No, the axis must be specified: torque = (distance from the axis) X (force). (X is the vector cross-product in this case - meaning the angle also matters.)No, the axis must be specified: torque = (distance from the axis) X (force).
