2. 1D Motion / Kinematics

Under what circumstances would a vector have components that are equal in magnitude?

Which of the following combinations correctly pairs a vector quantity with its corresponding unit?

If Sue walks home and her home is defined as the origin ($O$), what is her displacement ($d$) upon arriving home?

Which of the following is a pair of vector quantities?

If a vector lies in the first quadrant of a standard Cartesian coordinate system and motion is along a straight path, which of the following conditions will result in both components of the vector being positive?

A force of magnitude $10$ $N$ acts at an angle of $30°$ above the positive $x$-axis in the $xy$-plane. How can this force be expressed as a Cartesian vector?

If $\overrightarrow{a}$ and $\overrightarrow{b}$ are vectors, what is the magnitude of $\overrightarrow{b}-3\overrightarrow{a}$ in terms of the magnitudes of $\overrightarrow{a}$ and $\overrightarrow{b}$, assuming they are in the same direction?

Why is $d$istance alone insufficient to determine an object's location relative to another object?

Which of the following best describes $d$isplacement, given that it has both magnitude and direction?

Which of the following best explains how $velocity$ differs from $speed$, and why $velocity$ is considered a $vector$ quantity?
