Vector quantities can be said to be physical quantities that have a number of units(magnitude) and direction.
Vector quantities include the following: Velocity, torque, displacement.
The length of a vector can be said to be the magnitude.
The length of a vector represents the magnitude and the direction of the quantity is the direction which the vector is pointing.
The magnitude of a vector is the length of the vector.
The magnitude is denoted as |v|.
