Questions and Answers

How is distance different from displacement?

Distance and displacement are both scalar quantities
Displacement has no direction, while distance has both magnitude and direction
Distance and displacement are essentially the same
Distance has no direction, while displacement has both magnitude and direction (correct)

What is displacement?

The distance covered by a moving object with respect to time
The total length covered by a moving object
The shortest distance between two points with magnitude and direction (correct)
The distance between the starting and final positions with no direction

What do students learn in Class 9 Science Chapter 8 Motion?

Describing circular motion only
Describing the motion of objects along a straight line and expressing motions through simple equations and graphs (correct)
Describing the motion of objects in three dimensions
Describing the motion of objects with complex equations

Flashcards

Displacement

The shortest distance between two points, considering both the magnitude (how much) and direction (where).

Distance

The total distance traveled by an object, regardless of direction. It only considers the magnitude (how much).

Can displacement be zero?

When an object starts and ends at the same position, the total displacement is zero. Even if the object traveled a significant distance, the net change in position is zero.

What is studied in Class 9 Chapter 8: Motion?

Motion along a straight line is studied. Students learn to represent motion using equations and graphs.

Study Notes

Motion and Distance

Distance is the total path traveled by an object, whereas displacement is the shortest distance between the initial and final positions of the object.
Displacement is a vector quantity that has both magnitude and direction.

Class 9 Science Chapter 8

Students learn about the concept of motion, including distance, displacement, speed, velocity, and acceleration.
They understand the differences between distance and displacement, and how to calculate them.

Displacement

Displacement can be zero when an object returns to its initial position, having traveled a certain distance.
For example, if an object moves in a circle and ends up at the starting point, its displacement is zero, but the distance traveled is not zero.

CBSE Syllabus 2023-24

The renumbered chapter for Motion in the CBSE Syllabus 2023-24 is Chapter 3.
