What Is A Vector Quantity. The difference between scalar and vector quantities is an important one. But anyways let us delve deep into the meaning and we shall try to gauge the concept with some references which would make this crystal cle.
Physical quantities that can be fully described by giving a single number and an appropriate unit are called a Scalar quantity. An example of a vector quantity would be velocity. On the other hand, multi-dimensional quantities are explained by vector quantity.
Speed is a scalar quantity and Velocity is a vector quantity.
For example velocity is a vector quantity but a similar term speed is a scalar A vector quantity is one which has magnitude and direction both.
A vector quantity is an instance of an equivalence class of directed line segments whose lengths and directions are equal. These always have the same magnitude but speed has no direction. Sometimes, the direction of a number or quantity is as important as the number itself.
