What is the difference between distance and displacement?
What is the difference between distance and displacement?
Distance is the magnitude of the length covered by a moving object and has no direction, while displacement is the shortest distance between two points with magnitude and direction.

Study Notes
Distance vs Displacement
- Distance: Total length traveled by an object in a certain time, regardless of direction.
- Displacement: The shortest distance between the initial and final position of an object. It has both magnitude and direction, making it a vector quantity.
Chapter 8: Motion
- Chapter 8 in Class 9 Science focuses on the concept of motion, including its types, speed, velocity, and acceleration.
- The chapter is renumbered from Chapter 8 to Chapter 7 in the updated CBSE Syllabus 2023-24.
Chapter 7: Motion (CBSE Syllabus 2023-24)
- The renumbered chapter 7 delves into the crucial concepts of distance, displacement, speed, velocity, acceleration, and their applications in real-world scenarios.
Displacement Definition
- Displacement refers to the change in position of an object.
- It is a vector quantity, meaning it has both magnitude (amount) and direction.
- Displacement can be zero even if the distance traveled is not zero.
- For instance, an object moving in a circle returns to its starting point, resulting in zero displacement despite traveling a considerable distance.
