Vector Components and Resultant Vectors

The video tutorial explains how to sketch the sum of two vectors using the triangle rule. It begins with a manual example of vectors A and B, detailing how to find their component forms and sketch them on a coordinate plane. The tutorial then demonstrates how to sum the X and Y components of the vectors to find the resultant vector. Finally, it provides an example using an online graphing tool to sketch vectors V and W, emphasizing the use of the triangle rule throughout.

What is the first step in using the triangle rule for vector addition?

• Add the x-components of both vectors.

• Draw a perpendicular line from the origin.

• Place the initial point of the second vector at the terminal point of the first vector.

• Calculate the magnitude of each vector.

What are the x and y components of Vector A?

• X: 1, Y: 5

• X: -4, Y: -2

• X: 2, Y: 3

• X: -1, Y: 4

How do you find the resultant vector using the triangle rule?

• By drawing a line from the origin to the terminal point of the second vector.

• By adding the magnitudes of the two vectors.

• By subtracting the y-components of the vectors.
