a quantity having direction as well as magnitude, esp. as determining the position of one point in space relative to another.
SIMPLE DEFINITION: vectors find the direction (where an object is going) and the magnitude
A vector is a numerical value in a specific direction, and is used in both math and physics. The force vector describes a specific amount of force and its direction. You need both value and direction to have a vector. Both. Very important. Scientists refer to the two values as direction and magnitude. The alternative to a vector is a scalar. Scalars have values, but no direction is needed. Temperature, mass, and energy are examples of scalars.
