The components of a vector are the parts of the vector that are to each other.

Which of the following quantities is a vector?

A vector has a magnitude of $5$ units and points $37°$ above the positive x-axis. What is the component form of this vector?

Which of the following correctly represents the vector $\overrightarrow{c}$ if $\overrightarrow{c}=1.5\overrightarrow{a}-3\overrightarrow{b}$?

Suppose in Figure 1, you are given two vectors: $A$ with a magnitude of $3$ units pointing east, and $B$ with a magnitude of $4$ units pointing north. Which of the following combinations of these vectors results in the largest possible magnitude?

When two displacement vectors of equal magnitude point in exactly opposite directions, what is the resulting displacement when they are added together?

In physics diagrams, the magnitude of both scalar and vector quantities is represented by the length of a line. What property of the line indicates this magnitude?

If vector $a$ has an x-component of $3$ and vector $b$ has an x-component of $-2$, what is the sum of the x components of vectors $a$ and $b$?
