Vector Addition

An arrow-tipped line segment having a specified length and direction is called a

• algebraic representation.

• displacement vector.

• graphical representation.

• Magnitude vector.

In printed materials a vector is often represented as an italicized letter in boldface type. This form is called

• an algebraic representation.

• a resultant vector.

• a displacement vector.

• a graphical representation.

A resultant vector is

• equal to the sum of one vector.

• equal to the sum of two or more vectors.

• equal to the difference of one vector.

If two vectors to be added are at right angles, you will need to

• just add them together.

• use the Pythagorean theorem.

• use the Law of Cosines.

• subtract the smaller for the larger.

The process of breaking a vector into its components is called

• vector resultant.

• vector displacement.

• vector coordinates.

• vector resolution.

The magnitude and sign of component vectors are called the

• components.

• resultants.

• displacements.

• unknowns.

If two vectors to be added are at some angle other then 90 degrees, then you can use

• the Pythagorean theorem.

• vector addition.

• the Law of Cosines.

• Charles Law.

Placing vectors in a coordinate system that you have chosen makes it possible to decompose them into components along each of the chosen coordinate axes.

• True

• False
