Some physical quantities, like mass and temperature, are scalars, described by a single number.
Other quantities, like displacement, velocity, and force, are vectors. They have both a magnitude (number) and a direction.
Vectors are represented as arrows. The arrow's length signifies the quantity's magnitude, and its direction indicates the vector's orientation.
Vectors can be moved anywhere on a coordinate system, keeping their length and direction the same.
