Question

Path length is always positive, while displacement can be positive, negative or zero first of explain this statement by a suitable example

Answer 1

Let's review. Displacement is a vector quantity, so we need to specify a magnitude and direction in order to fully characterize it. Unlike distance, which can only get larger on any path taken, displacement can be positive, negative, or zero. Displacement is zero when you start and end at the same spot

Answer 2

Yes.

If the starting point and end point are the same , with a distance being traversed, then displacement would be zero , while distance won’t.

For example , a square ABCD of sides 1 km . If you start at point A and traverse the entire perimeter of the square and return at point A , then displacement would be 0 km , but distance covered would be 4x1 km = 4 km.
