Answer 1

Let's take an example to understand this:

A car travels from A to B with some speed and return back using the same pathway.

Assume that the distance covered by the car is 'x' km.

Since the car starts from A to B, then returns to A point again. So, the distance covered by the car is twice of the distance i.e. 2x km. Also, the initial and final points of the car are same i.e. A point. So, the displacement of the car is 0 km.

Let's take one more 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 (Ram) is 0 km. As his initial and final points are same (here initial and final point is his house).

From above examples we can say that if an object has moved through some distance it can have zero displacement. (If the initial and final points are same. Also, if there is no distance covered by the object.)

Answer 2

Answer :-

Yes , Displacement can be equal to zero even when an object have moved a certain distance.

To explain it let us consider their definitions :-

◾ Distance :- The length of actual path transversed by the object.

◾ Displacement :- The length of shortest possible path between two points.

To explain it more clearly let us consider this example :-

• An object complete 2 revolution around a circular path with a fixed center and radius.

So we will have the total distance = 2. 2πR

But displacement = 0 as it will be at its starting place after 2 revolution.

So we can also form a Result on it's basis

→ Distance is always greater than or equal to Displacement.

In other words Displacement can never be greater than Distance.
