Concept:Distance is a scalar quantity, while displacement is a vector quantity.
Explanation:Distance gives the total length of the path travelled.
It has only magnitude and no direction.
So, distance is a scalar quantity, not a vector quantity.
Displacement gives the shortest straight-line separation from the initial to the final position.
It has both magnitude and direction.
So, displacement is a vector quantity.
Both distance and displacement are measured in meters (
m).
Distance also has dimension of length, which is a correct statement.
Thus, the incorrect statement is: “Distance is a vector quantity.”
Answer:Option D
