Question

explain the 1.unit vector
2.equal vector
3.negative vectors
4.cointial vectors
5.collinear vector
​

Answer 1

1. Vectors having magnitude as 1 is called unit vector.
2. Vectors which have equal magnitude and also in same direction is called equal vectors.
3. Vectors which have same magnitude but opposite in direction is called negative vectors.
4. Vectors having initial point or initial term as same is called coinitial vectors.
5. Vectors which lie on other vector making an angle of 0° or 180° is called collinear vector.

Answer 2

$\huge{\sf Vectors \colon}$

• Any physical quantity which has a magnitude and specifices direction is known as a Vector Quantity

• In other words, directional extension of scalars

Unit Vector

• They have a magnitude one

• They move in a specific direction

• They are expressed as a product of their magnitude and direction

Equal Vectors

• Vectors which have the same magnitude

• They also move in the same direction

Negative Vectors

• Vectors which have same magnitude

• But they move in different directions

Coinitial Vectors

• Vectors which start from the same point

Collinear Vectors

• Vectors which are parallel to eachother, meaning the angle between them is 0°
