Question

A body thrown vertically upwards reaches a maximum height ‘h’. It then returns to

ground. Calculate the distance travelled and the displacement.

Answer 1

Displacement is the actual length gap between starting & finishing points.
In this case, they are same, so
Net displacement is zero.

Distance travelled is the length which is actually covered by the moving body.
As the body goes up for "h" length and comes down "h" length, so
Net distance travelled= h+ h= 2h

Hope it was easy for you

Answer 2

Answer: The body is coming back to the initial position, so the net displacement is zero.

Explanation:

Step 1, Finding the distance

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

Step 2, Finding the displacement

• We know that the shortest distance between the initial and final positions of the body is called displacement.
• 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.
