Question

A body thrown vertically upward reaches a maximum height H. It then return to ground. Calculate the distance travelled and displacement.

Answer 1

Step 1, Finding the distance

1. As we know that the total length of the journey is the distance.
2. The distance will be the sum of distance traveled by the body when thrown upwards and distance traveled while coming down
3. So,Distance = H+H = 2 H

Step 2, Finding the displacement

1. We know that the shortest distance between the initial and final positions of the body is called displacement.
2. In this case, the body is coming back to the initial position so the net displacement is zero. Here initial the and final position is the same.
