Lesson: Distance and Displacement High School PhysicsPhysics
In this lesson, we will learn how to define distance as the length of a path between two positions and to define displacement as the straight line distance between two positions.
Sample Question Videos
A rover on Mars is initially facing north. The rover travels 300 m in the direction it is facing, turns to its left and travels 200 m in this new direction, turns left again and travels 500 m in the direction it is now facing, and turns left once more and travels 100 m in the direction that it is now facing.
What is the rover’s net displacement east of its initial position?
What is the rover’s net displacement north of its initial position?
A woman starts at the point A shown in the diagram and walks up two flights of stairs that are both 6 m in height and walks to point B, which is directly above point A.
What is the woman’s upward vertical displacement?
What is the woman’s net horizontal displacement?
A tourist wandering around a city walks 965 m east, then 244 m south, then 139 m west, then 760 m north, then 826 m west, and then finally 44 m south before stopping for a rest. How far is the tourist displaced from the point they started walking from?
