It is a vector quantity, which has both direction and magnitude.

Here he claims that the "up" means it is a vector quantity.

A vector quantity requires three numbers to define its direction.

We are dealing with the vector quantities of velocity in this question.

Because of these characteristics, forces are classified as "vector quantities".

Remember: velocity is a vector quantity made of both speed and direction.

In two or more dimensions, the are vector quantities.

In handwriting, a wavy line is usually drawn under vector quantities.

Magnetic fields are vector quantities characterized by both strength and direction.

It is thus a vector quantity with dimension length/time2.

Decide your scale by looking at the sizes of your vector quantities.

Draw arrows of appropriate length and direction to represent vector quantities.

Acceleration, velocity, force and displacement are all examples of vector quantities.

In case of more than one spatial dimension, wavenumber is a vector quantity.

Velocity is a physical vector quantity; both magnitude and direction are needed to define it.

Quantities that have both a magnitude and a direction are known as vector quantities.

Note that the displacement is a vector quantity.

Dipoles can be characterized by their dipole moment, a vector quantity.

Therefore, pressure is a scalar quantity, not a vector quantity.

Add and subtract vector quantities by the graphical method.

Some extreme microlensing events can only constrain one component of these vector quantities.

You can not set a vector quantity equal to a scalar quantity.

This resolution defines weight as a vector, since force is a vector quantity.

Momentum, having mass and velocity, is also a vector quantity, but inertia is not.

These vector quantities point in the direction of the relative motion of the lens with respect to the source.
