Problem
State the mathematical expression for the displacement of a particle moving along a straight line in terms of its initial position and final position .Intuitive explanation
Displacement measures how far and in which direction an object actually moved—it's purely about the start and end points, not the path taken. The key insight is that displacement is a vector quantity, so direction matters: it's always the final position minus the initial position, which automatically captures both magnitude and sign (positive for forward, negative for backward).
