An object has moved through a distance can it have zero displacement if yes support your answer with an example

Hint: The distance of the moving object is the path covered by the object while moving. The change in the initial and the final position of the object when it is moved is known as the displacement. Complete answer: When the object is moving from one point to another point. The path covered by the objects cis known as the distance of the object. Distance of the object is the scalar quantity. So, it has only magnitude. It doesn’t have direction for movement. Another quantity of the moving object apart from distance is known as the displacement of the object. The displacement is the distance between the initial and the final position of the object. The displacement is the vector quantity. So, it requires magnitude as well as the direction. Example: Consider an object moving in the circular path. The object starts from point A and reaches the same point. The distance of the object is given as: $s = 2 \pi r$ Where, r is the radius of the circle. The displacement of the object is the distance from the initial position and the final position of the object. In circular motion, the initial and the final position of the object are the same. So, the displacement of the object is zero. Note: The distance of the moving object can never be zero. Distance can be very small, but not zero. The displacement of the object can be zero because it is the vector quantity. So, the direction is also required for its description. If the particle is moving 2 m up and then 2 m down. Their direction i...

Q 1. An object has moved through a distance. Can it have zero displacement? If yes support your answer with an example. SOLUTION: Yes, the object instead of moving through a distance can have zero displacement. Example: If an object travels from point A and reaches to the same point A, then its displacement is zero. Q 2. A farmer moves along the boundary of a square field of side 10 m in 40 s. What will be the magnitude of displacement of the farmer at the end of 2 minutes 20 seconds? SOLUTION: Q 3. Which of the following is true for displacement? (A) It cannot be zero. (B) Its magnitude is greater than the distance travelled by the object. SOLUTION: A. False. B. False Q 4. Distinguish between speed and velocity? SOLUTION: Q 5. Under what condition(s) is the magnitude of average velocity of an object equal to its average speed? SOLUTION: The magnitude of average velocity of an object is equal to its average speed if the object moves in a straight line in a particular direction. Q 6. What does the odometer of an automobile measure? SOLUTION: The odometer of an automobile measures the distance travelled by a vehicle. Q 7. What does the path of an object look like when it is in uniform motion? SOLUTION: It is a straight line. Q 8. During an experiment, a signal from a spaceship reached the ground station in five minutes. What was the distance of the spaceship from the ground station?

Yes, an object can have zero displacement even when it has moved through a distance. This happens when final position of the object coincides with its initial position. For example, suppose an object starts from point A and after covering a distance of say 50 meters, reaches point B. Then it turns back and comes to point A. Here, distance covered by the object = AB + BA = 50 m + 50 m = 100 m While displacement of the object = 0 (As final position is same as initial position)

Yes, an object which has moved certain distance can have zero displacement as we know displacement is the shortest distance between the starting or initial point and end or final point of an object which has moved. For eg. if a person starts moving from point A and comes back to point A then his displacement is zero.
