Question

A body thrown vertically upwards reaches a max height h it then vertically returns to the ground calculate the distance travelled and displacement

Answer 1

Answer:

Distance = 2h

Displacement = 0

Explanation:

Vertically Upwards Motion:

Distance travelled till the highest point = 'h'

Vertically Downward Motion:

Distance travelled from the highest point = 'h'

Hence Net Distance travelled Upward and Downward is = h + h = 2h units

Displacement is the distance between Initial and Final Points of Motion. Since the Initial and Final points of the motion are same, the Net Displacement is 0.

Hope it helped !!

Answer 2

Answer :

We know that the displacement is the shortest distance and the actual length gap between the origin and finishing point. It is a vector quantity which has magnitude as well as direction.

According to the information,

If a body thrown vertically upwards reaches a max height "h" it then vertically returns to the ground, no displacement is here.

So, the net displacement is "0".

.°. The net displacement is "0".

The total the total length of the journey that is the distance travelled by the moving body goes up for length "h" and comes down "h" length. It is a distance which has only magnitude. It has no direction.

Here, "h" is the length of the moving body.

So, the net distance covered by the moving body is = h + h = 2h

.°. The net distance covered by the moving body is = "2h" units
