उत्तर
| Distance | Displacement |
| It is defined as the length of the actual path travelled by an object in motion. | It is defined as the shortest distance between the starting and finishing points. |
| It is a scalar quantity. | It is a vector quantity. |
| The values of distance are always positive. | The values of displacement can be positive, negative or zero. |
