Question

A ball is thrown upwards and it goes to the height 100 m and comes down
1) What is the net displacement?
2) What is the net distance?

Answer 1

A ball is thrown upwards and it goes to the height 100 m and comes down.

1) What is the net displacement?
Ans. Displacement for the above situation is 0. As we know, that displacement is the shortest path from the initial to the final point. Here, the initial and the final points are the same, and hence, it takes no time to travel. So, the displacement is 0.

2) What is the distance?
Ans. Distance for the above situation is 200 m. Here, the ball has to cover a distance of 100 m and while coming back, again it has to cover the same distance, hence, the distance to be covered here is 200 m.

100 + 100 = 200 

Hope this answer might help you

Answer 2

Answer:

Distance - 100+100 =200

Displacement - 100-100 = 0
