#### Definition of Vector

A vector is a quantity described by both magnitude and direction. Velocity (for example 2.5 m/s west) is a vector, whereas mass (3 kg) is a scalar quantity.

#### Definition of Resultant

A resultant is a vector formed by combining two or more vectors.

#### Definition of Component

Components are vectors which, when combined, form a resultant. Orthogonal components are components that are at 90 degrees to each other. They are normally parallel to the axes of a reference system.

#### Definition of Resolution

Taking apart a vector into components is called "vector resolution" or "resolving the vector."
