# Scalar , vector and type of vector

Physical quantities are of two types vector and scalar

### Scalar zodiac -

Some physical ratios are such that only results. They do not have any direction, for example, mass, distance, time, move, volume, density, pressure, work, energy power, charge, validity stream, potential, heat, special heat, and frequency. Such amounts are called scalar
Any scalar quantity can be fully expressed by only one number and one quantity, for example, the star's mass is 200 kg

### Vector Zodiac -

There is some physical amount of which along with the result there is also a tale which follows the vector rules (the triangle method of yoga and the method of the parallelogram), for example, position, displacement, velocity, acceleration, force, weight, Momentum, impulse, discrete area, magnetic force area, the density of the current, etc. Such amounts are called vector zodiac signs.
To fully express any vector sum, it is necessary to mention the direction along with the result of the amount. If we are to tell a person the position of our college, that our college is 2 kilometers from the station, then our point will be incomplete and that person will not be able to reach college. If we say that our college is about 2 kilometers north of the station then it will understand the position of the college. This condition is a vector sum.

### Formation of vector quantities -

Any vector of a vector is given by an arrow in Assigned. This arrow is called a vector, the length of the arrow, the result of that amount, and the arrow's arrow display the direction of that amount.

Suppose a car is being driven from the speed of 10 meters / second to the east, and second, the velocity of the velocity given in the picture to the velocity is being run in the direction of north-east with the speed of 20 meters/second. To denote the vector we were assumed that 1 cm length, 5 meters / second represents the velocity, the vector of the tax is 2 cm length and the tip is towards the east. The car vector is 4 cm long and its people towards the northeast

### The same vector -

If a vector depicts a vector, then it is not affected by the parallel displacement. So all the same vectors whose length and the result are the same in the direction of the direction called normal vectors

### opposite vector -

The opposite vector is two parallel vectors whose result is equal but the directions are called the opposite vector

### acronym vector -

The vector whose result is one is called acronym vector

If there is a vector, which is the result of the angle vector whose direction is in the direction of the work sector, one is written in the same direction
Thus the angle vector in the angle vector is written as the multiplication of the vector to any vector

### Symbolic integral vector -

The lymphatic axis, X-axis, Y-axis, Z-axis integral integer vector are written as i, j, k, respectively

### Zero vector -

The vector whose result is zero is called zero vector, it writes from the Zoe, the initial and final point of the zero vector is coincidental, its direction is uncertain

### Properties of Zero Vector-

1  The permit vector A ⃗ plus the sum of the zero vector is equal to the sum of the permit vector

2  Multiplication of zero vector permit number is equal to zero vector

3  Permit vector is equal to zero by zero the vector
