(A)       Vector Quantities    Scalar Quantities        $(1)$ Physical quantities that require both magnitude and direction for their complete specification are called vector quantities.    $(1)$ Physical quantities that can be described by their magnitude only are called scalar quantities.        $(2)$ Examples: velocity,acceleration,force,weight,displacement,momentum,etc.    $(2)$ Examples: speed,mass,volume,size,temperature,amount of substance,power,work done,pressure,time,etc.        $(3)$ While representing these quantities,both magnitude and direction must be stated.    $(3)$ While representing these quantities,only their magnitude is required,i.e.,the numerical value with units.        $(4)$ These quantities cannot be added algebraically; they follow vector addition laws.    $(4)$ These quantities are added or subtracted using simple algebraic rules.
