How to graph and multiply a vector by it's resultant

The video tutorial explains the concept of scalars and their effect on vectors. It begins with an introduction to scalars, followed by a demonstration of graphing a vector. The tutorial emphasizes how multiplying a vector by a scalar affects its magnitude but not its direction, contrasting it with a resultant vector that changes both magnitude and direction.

Describe the process of graphing a vector as mentioned in the text.

What does the vector 'u' look like according to the text?

What is a scalar and how does it affect a vector?

Explain the difference in magnitude and direction when multiplying a vector by a scalar.

What should students understand about the resultant vector compared to the scalar multiplication of a vector?
