1. Displacement:
* Definition: Displacement is the straight-line distance between an object's starting point and its ending point. It's a vector quantity, meaning it has both magnitude (length) and direction.
* Direction: Displacement tells you the direction the object moved *overall*, regardless of the path it took. For example, if someone walks 5 meters north, then 5 meters south, their displacement is 0 meters because they end up back at their starting point.
* Units: Displacement is usually measured in meters (m), kilometers (km), or other units of distance.
2. Distance:
* Definition: Distance is the total length of the path an object travels. It's a scalar quantity, meaning it only has magnitude (length).
* Direction: Distance doesn't care about direction. It simply measures how much ground was covered.
* Units: Distance is also measured in meters (m), kilometers (km), or other units of distance.
Example:
Imagine a person walking 10 meters east, then 5 meters north.
* Distance: The person traveled a total distance of 15 meters (10 meters + 5 meters).
* Displacement: The person's displacement is about 11.2 meters, in a direction approximately 26.6 degrees north of east (using the Pythagorean theorem and trigonometry).
In summary:
* Displacement tells you the *net change in position* from start to finish, considering both distance and direction.
* Distance tells you the *total path length* traveled, regardless of direction.
