Question

deplacement can be zero when distance travel is not zero but when distance travelled is zero displacement must be zero justify​

Answer 1

There are two cases where displacement must be zero -

• If the object move has moved some distance and returned at the same initial point in the end then the displacement is zero.
• If the object doesn't travel any distance then displacement must be zero.

Let's take an example to understand this.

In the first case:

Suppose that you went to the school which is 10 km away from your house. Your initial point is your house from where you start moving.

Now, after school, you return back to your home from the same path. Here, you cover the same distance again i.e. 10 km.

The total distance covered by you is (10 + 10)km i.e. 20 km.

But as you return to the same point (means the starting point from where you start and the starting point is your house). Then the displacement is zero.

In the second case:

If you don't went to school then your distance travelled is zero, also displacement is zero.
