Question

A body thrown vertically upwards reaches a maximum height h . It then returns to ground. The distance and the displacement travelled by the body respectively are

Answer 1

Answer:

distance = length of the path traveled = 2h ( h upwards and h downwards )

displacement = shortest distance between initial and final point

here initial and final point are same

So

displacement = 0

HOPE IT IS HELPFUL

Answer 2

Given: A body is thrown vertically upwards. It reaches a maximum height h. It then returns to ground.

To find: Distance and displacement travelled by the body

Solution: Distance travelled by a body is the total length covered by the body during the journey. It is a scalar quantity.

Here, it goes to a height h and then returns covering the same height h.

Therefore, total length covered

= Length covered going up+ length covered coming down

= h+h

= 2h

Displacement is the shortest path of a body between its starting and end point.

Here, the body goes up but returns down to the same position after falling down. The starting point is same as the end point.

Therefore, displacement

= Shortest path between starting and end point

= 0

Therefore, the distance travelled by body is 2h and displacement of the body is 0.
