Question
Read each statement below carefully and state with reasons, if it is true or false:
The total path length is always equal to the magnitude of the displacement vector of a particle.
✓

Answer

False.
Explanation:
Total path length is a scalar quantity, whereas displacement is a vector quantity. Hence, the total path length is always greater than the magnitude of displacement. It becomes equal to the magnitude of displacement only when a particle is moving in a straight line.
