What is the difference between the concepts of “path” and “movement”? Can they be equal in size to each other? In which case?

The path is a scalar value equal to the length of the imaginary line along which the body moved.
A move is a vector drawn from the point at which the movement began to the end point.
Example. When moving, the point has passed half of the circle. The length of half of the circle in this case will be the length of the path, and the vector connecting the start and end points (the length of the vector is equal to the diameter of the circle) will be the displacement.
These two quantities can never coincide, since they have a different nature (vector and scalar).
The path and the absolute value of the corresponding displacement vector can be equal:
– the movement is carried out in a straight line.
– movement along a curve is divided into a number of small segments tending to infinity. The absolute amount of displacement on each of these segments is almost equal to the corresponding path.
