Answer:
The magnitude of displacement of a particle is either less or equal to the path length of the particle between two points.
Explanation:
The physical quantity displacement can be calculated as the shortest distance between the final and initial positions of an object. If we measure the total path length of an object, then the obtained quantity will be distance, not displacement.
For the motion of an object, the magnitude of distance is usually higher than that of the displacement. But if the motion of the object is along a straight path, then the magnitudes of both displacement and distance will be equal. Because both the quantities are measured along the same straight-line path. The magnitude of displacement can never exceed the value of distance, as the former is the shortest distance measured between the final and initial points.
