Module 2

Question 1

It is any quantity that has magnitude but has no direction.

Answer 1

Scalar

Question 2

It is any quantity that has magnitude and direction.

Answer 2

vector

Question 3

It is the simplest projection, wherein the quantity is represented with an arrow pointing to a specific direction, usually in one of the four cardinal directions (NESW).

Answer 3

one-dimensional

Question 4

This projection shows the vector value represented by an arrow pointing in a direction specified by two (2) components: the x- and y-axes, which is measured by an angle.

Answer 4

two- dimensional

Question 5

This complex form of projection represents the vector with an arrow that uses three components: x, y, and the z-axis.

Answer 5

the three-dimensional

Question 6

[Two-Dimensional Components]
What are the steps in splitting a vector into its components?

Answer 6

1. Sketch the vector on the Cartesian coordinate system based on the given information.
2. Based on the quadrant where it is located, determine the sign of each component.
3. Determine which trigonometric function will give the x- and y-components.
4. Multiply the magnitude of the vector to the appropriate trigonometric function of the angle to obtain the magnitude of the component.
5. Affix the sign of the components as obtained in step 2.

Question 7

This method is used for accurately drawn vectors, or for two (2) vectors of different sources. Simply put, using this method requires all that has been learned in trigonometry and basic geometry.

Answer 7

parallelogram method

Question 8

It is a vector whose value shows only the direction because its magnitude is equal to one. It is similar to the unit circle in Trigonometry because it represents all trigonometric functions with measurement in all quadrants equal to one.

Answer 8

unit vector
