Question: Which of the following is true for displacement?
A It cannot be zero if an object has travelled some distance
B Its magnitude is always equal or greater than the distance travelled by an object
C It is a scalar quantity
D Its magnitude is equal to or less than the distance travelled by an object
Answer: Its magnitude is equal to or less than the distance travelled by an object
| Aspect | Description |
| Introduction | · Displacement is defined as the change in position of an object, measured in a straight line starting from the initial point to the final point. · It is a vector quantity having both magnitude and direction. |
| Mathematical equation | Δ𝑑 = 𝑑𝑓 – 𝑑𝑖 |
| Magnitude | · Displacement represents the shortest distance between the two points. · It is always equal to or less than the total distance traveled by the object. |
| Type of quantity | · Displacement is a vector quantity because it has both magnitude and direction. |
| Example | · If an object moves 10 m east and then 5 m west, then its displacement well be 5 meters east. |
