This chapter discusses the quantities used in engineering and science, and can be divided into two groups. Scalar quantities have a size or magnitude only and need no other information to specify them. Thus, 10 cm, 50 s, 7 l, and 3 kg are all examples of scalar quantities. Vector ...

How to Distinguish Between Vector and Scalar Quantities Step 1:Identify the units for the quantity and determine if the quantity described has a direction associated with it. Step 2:Identify the quantity as a vector or a scalar. Vector quantities involve a magnitude (number) with units and a ...
A physical quantity is the measurable and quantifiable physical property that carries unique information with it. Based on the dependency of direction, physical quantities can be classified into two categories — scalar and vector. Let us now discuss wha
Mathematical operations within two and more than two scalar quantities result in providing only scalar quantities. In the case of an operation between a scalar and a vector quantity, the result is provided as a vector quantity. Operation The result of a mathematical operation within two and even...
Scalar quantitieshave a size or magnitude only and need no other information to specify them. Thus, 10 cm, 50 sec, 7 litres and 3 kg are all examples of scalar quantities. Vector quantities have both a size or magnitude and a direction, called the line of action of the quantity. ...

Tutorials including examples with detailed solutiond on the addition and scalar multiplication of vectors are presented. Vectors are mathematical quantities used to represent concepts such as force or velocity which have both a magnitude and a direction. The figure below shows vector v with initial ...
