Question

1. An object has moved through a
distance. Can it have zero
displacement? If yes, support
your answer with an example.

Answer 1

Answer:

PLEASE MARK MY ANSWER AS THE BRAINLIEST.

Explanation:

Yes, a object can have 0 Displacement even though it has moved some distance. Example:- A body is moving in uniform circular motion. Its distance changes but its Displacement becomes 0 when it returns to its initial point.

Answer 2

Yes, an object can have zero displacement if it moved though some distance.

Displacement is defined as the shortest path travelled by a body between the initial and final points. Whereas, distance is defined as the total path covered by the body.

Let's take an example to understand this.

Ram want to a market to buy some fruits. He starts from his house. Here, his house is the initial point from where he starts moving and market is the final destination or point where he want to reach.

Assume that, from his house to market he travelled a distance of 15 km. Now, after buying fruits he return backs to his house using the same pathway. Again the distance covered by him is the 15 km. So, the total distance covered by him is 30 km. Whereas, the Displacement covered by him is 0 km. As his initial and final points are same (here initial and final point is his house).

Cases where displacement can be zero -

• If the initial and final positions of object or body are same than displacement can be zero.
• If the object doesn't move from it's position.
