Common mistake
Confusing Distance with Displacement
Students often confuse distance with displacement, thinking they are the same because both relate to how far an object moves.
Emphasize that distance is a scalar quantity representing how far an object has traveled, regardless of direction, while displacement is a vector quantity that includes both distance and direction from the starting point.
