Vector Components and Changes in Direction

The video tutorial explains how to find the components of vector AB by breaking it down into changes in the X and Y directions. Starting from point A (4, 4) and ending at point B (-7, 8), the tutorial demonstrates how to calculate the change in X as -11 and the change in Y as 12. The video also illustrates how these changes can be visualized as vectors in the X and Y directions, which together form vector AB.

What is the primary focus when discussing vector components in this context?

• Determining the vector's direction

• Calculating the magnitude of the vector

• Breaking the vector into x and y components

• Finding the angle of the vector

How do you calculate the change in the x component of a vector?

• By multiplying the initial and final x values

• By subtracting the initial x value from the final x value

• By dividing the final x value by the initial x value

• By adding the initial and final x values

If a vector starts at x = 4 and ends at x = -7, what is the change in x?

• 3

• -3

• -11

• 11

What does a negative change in the x component indicate?

• A decrease in the x direction

• A change in the y direction

• An increase in the x direction

• No change in the x direction

How is the change in y component calculated?

• By subtracting the initial y value from the final y value

• By adding the initial and final y values

• By dividing the final y value by the initial y value

• By multiplying the initial and final y values

If a vector starts at y = 4 and ends at y = 8, what is the change in y?

• -4

• 12

• 4

• -12

What does a positive change in the y component indicate?
