Is Distance a Scalar Quantity

Introduction to distance:
The physical quantity which has only magnitude but no direction is called scalar quantity or scalars.  Mass, length, time, distance covered, speed, temperature, work, etc. are few examples of scalar quantity.  The scalars can be added, subtracted, multiplied and divided by ordinary laws of algebra.  The scalar is specified by mere number and unit, where number represents its magnitude.  A scalar may be positive or negative.  A scalar can be represented by a single letter.

I like to share this Define Scalar with you all through my article.

Explanation to distance:


Distance: The total path length or distance of an object during motion in a given time is the length of actual path traversed by the object in the given time.  The total path length is the actual distance traveled by an object in the given time during motion.  Total path length (i.e. actual distance traveled) is a scalar quantity. Its value can never be zero or negative, during the motion of an object.

I have recently faced lot of problem while learning Frequency Formula, But thank to online resources of science which helped me to learn myself easily on net.

Description of distance as scalar quantity


A scalar quantity is a quantity with magnitude only.  It is specified completely by a single number, along with the proper unit.  For example: the distance between two points, mass of an object, temperature of a body and the time at which a certain event happened.  The rules for combining scalar are the rules of ordinary algebra.  Scalar can be added, subtracted, multiplied, and divided as the ordinary number.  For example, if the length and breadth of rectangle are 1m and 5m respectively, then its perimeter is the some of the length of the four sites, 1m + 5m + 1m + 5m = 12m.  The length of each side is a scalar and the perimeter is also a scalar.  Another example is suppose an object goes from A to C following the path ABC, in a certain time t then total path length traversed by object in time intervals t = AB + AC.  If the object goes from A to B, B to C and C to A in time interval t, then the total path length traversed by object in time t = AB + BC + CA.
