The best answer that describes displacement is:
"Displacement is a vector quality showing total length of an area traveled by a particular object."
This definition acknowledges that displacement is a vector quantity, which means it has both magnitude and direction, and it measures the shortest distance from the initial position to the final position of an object. However, it is important to note that while displacement does involve distance, it specifically refers to the difference in position and does not account for the total length of the path traveled. The correct emphasis should be on the change in position rather than the total length traveled.
Therefore, a more accurate answer would be:
"Displacement is a vector quantity showing the shortest distance and direction from the initial position to the final position of an object."
