Scalars are quantities that have magnitude only; they are independent of direction. Vectors have both magnitude and direction. The length of a vector represents magnitude. The arrow shows direction. EO 1.1 DEFINE the following as they relate to vectors: a. Scalar quantity b. Vector quantity Scalar Quantities Most of the physical quantities encountered in physics are either scalar or vector quantities. A scalar quantity is defined as a quantity that has magnitude only. Typical examples of scalar quantities are time, speed, temperature, and volume. A scalar quantity or parameter has no directional component, only magnitude. For example, the units for time (minutes, days, hours, etc.) represent an amount of time only and tell nothing of direction. Additional examples of scalar quantities are density, mass, and energy. Vector Quantities A vector quantity is defined as a quantity that has both magnitude and direction. To work with vector quantities, one must know the method for representing these quantities

Scalar





1.A physical quantity which has only magnitude is known as scalar quantity.





2. For ex: mass, length, time, work, etc.





3. Scalars obey algebraic rules for the operations like addition and multiplication.





4.A scalar can divide another scalar





#Vector





1.A physical quantity which has magnitude as well as direction is known as vector quantity.





2. For ex: velocity, displacement, acceleration, etc.





3. Vectors obey vector algebra for the operations like addition and multiplication.





4.Two vectors can never divide each other.

Vector quantities have both magnitude and direction. Scalar just has magnitude.

Very simple, scalers have magnitude and may or may not be direction. but it will not follow the law of vector addition as current. but vector will have magnitude and direction and also it must follow the law of vector addition. As force, electric field.
