In our day to day life, we come across many queries, such as the first one.
What is your height?
Let's say the second one, how should a football player hit the ball to give a pass to another player
of his team?
A possible answer to the first query may be one point six meters, that is the height.
A quantity that involves only one value, which is a real number, such quantities are called scalars.
However, an answer to the second query.
Is a quantity called force, which involves muscular strength, which is magnetism and direction in
which another player is positioned.
Such quantities are called vectors in mathematics, physics and engineering.
We frequently come across with both types of quantities, namely scalar quantities such as land mass
time distance.
And vector quantities like displacement, velocity, acceleration, force, momentum, etc.
Here are the examples of Vector's Abby and B.A. The point is from where the Victor Abby starts is called
its initial point and the point B where it ends is called it's terminal point.
The arrow indicates the direction of the vector.
So in the case of Victor B.
B is the initial point and it is the terminal point.
So consider the Victor OPIS over here.
Let's it all is the origin with coordinates zero zero zero, that is X, Y and Z coordinates are zero
zero zero of an origin and point B has coordinates X, Y and Z.
Then the magnitude of Victor Olby is given by magnitude of Victor Obbie equals root of X squared plus
Y squared plus Z Square.
Unit vector, a very important item that would be used in quantum computing and quantum mechanics,
a lot of vector whose magnitude is unity or one is called the unit vector, the unit vector in the direction
of a given vector, it is denoted by a gap.
Let's take an example of the unit vector.
Let's say I have a vector, do I plus three plaskett.
Unit vector is calculated as vector divided by its magnitude.
Over here, the magnitude is square root of 14.
And here goes your unit vector.
Just.
