Define displacement and explain how it differs from distance.

Displacement is defined as the distance moved in a particular direction from a starting point. Unlike distance, which only measures how far an object has traveled regardless of direction, displacement takes into account the direction of the movement, providing a vector quantity that can be positive or negative depending on the reference point.

This question tests the student's understanding of the concepts of distance and displacement, which are fundamental in physics. It requires them to not only define displacement but also to differentiate it from distance, demonstrating their grasp of vector versus scalar quantities.
