On the other hand, a vector quantity is defined as the physical quantity that has both magnitude as well as direction like force and weight. Unit vectors are vectors with a magnitude of 1. In mathematics, scalars are used as vector components, as well as in modules and normed vector spaces. A vector space is defined as a set of vectors, a set of scalars, and a scalar multiplication operation that takes a scalar k and a vector v to another vector kv.For example, in a coordinate space, the scalar multiplication (,, …,) yields (,, …,).In a (linear) function space, kƒ is the function x ↦ k(ƒ(x)). Scalar and vector quantities are treated differently in calculations. Vectors are quantities that are fully described by both a magnitude and a direction. - Studying the Motion of Objects, Scalars and Vectors: Definition and Difference, Distance and Displacement in Physics: Definition and Examples, Speed and Velocity: Difference and Examples, Acceleration: Definition, Equation and Examples, Uniformly-Accelerated Motion and the Big Five Kinematics Equations, Ticker Tape Diagrams: Analyzing Motion and Acceleration, What are Vector Diagrams?
