What is The Difference Between Distance And Displacement:



S.No
Distance
Displacement
           
         1.

It is the actual distance travelled by an object in the given time.

It is the shortest distance between the initial and final positions of the object in the given time.
            2.
It is a scalar quantity.

It is a vector quantity.
          
         3.
The distance travelled by an object in a given time is never negative or zero, but is always positive.

The displacement of an object in a given time can be positive, zero or negative.
          
         4.
The distance travelled by an object in a given time is either equal or greater than displacement but never less than displacement.

The displacement of an object in a given time can be equal or less than distance travelled but never greater than distance travelled.
          
         5.
The distance covered by an object between two positions can have many values, depending upon the path followed.

The displacement of an object between two positions has a unique value.
          
         6.
The distance travelled by the object between two positions tells the type of path followed.
The displacement of an object between two positions does not tell the type of path followed.
