01 - Intro to Vector Algebra | Scalar and Vector Quantities , Directed Line Segments, Magnitude of V
A Scalar is a quantity that is completely defined by a single value(magnitude) with an appropriate unit. Eg, mass, length, speed.
A vector is a quantity that is completely defined when we know not only its magnitude but also the direction in which it operates.
Eg. force, acceleration, velocity.
We shall also discuss
1. Line segment
2. Directed line segment
3. how to find the magnitude of a vector
4. Types of Vectors

You are good at what you are doing, I wonder why you have few subscribers. Keep the ball rolling 💪

you're welcome....

Please how did you get the 3 root 2(3√2) ?

[@SkanCityAcademy_SirJohn]

Okay. From the last but one step, we had root (18) So root (18) = root of (2*9) = root of (2) * root of (9) Root of (9) = 3 Hence = 3*root of (2)

The arrows on a vector represent the sense and not the direction which is given by the angle it subtends with a particular reference line. The initial point is known as the tail and the terminal point as the head of the vector. The video did not explain the unit vectors namely i, j and k.

[@SkanCityAcademy_SirJohn]

Thanks so much for your input. Unit vectors are discussed in the subsequent lessons.

[@gamerace8524]

Bro what does i and j stand for??????

[@SkanCityAcademy_SirJohn]

i and j are unit vectors along the x and y axis respectively

[@reedib5758]

What's I and j???

[@SkanCityAcademy_SirJohn]

I and j are unit vectors along the X and y axis respectively
