Answer:Difference Between Scalar and Vector
Scalar:
.It has only the magnitude
.Only one dimensional
.This quantity changes with the change in magnitude
.Normal rules of algebra are applicable here
.One scalar quantity can divide another scalar
.In the example of speed, time, etc, the distance between the points is a .scalar quantity, not the direction
vector:
.It has direction and magnitude
.It is multidimensional
.This changes with magnitude and direction
.There is a different set of rules known as vector algebra
.One vector cannot divide another vector
.Velocity could be an example because it is a measurement of the rate of change of an object’s position
