Question

Ria moves 5 m towards east then 5 m towards the north and again 5m towards the east. What was the distance covered her? What was the displacement?​

Answer 1

Answer:

Given :

Person moves 5m towards east and 4m towards east i.e, total Distance Travelled by person in x-direction is 9m

Then he travelled 5m towards south in y-direction

To Find :

Distance and displacement travelled by a person

Solution :

➞ Distance - Distance is total lenght of path covered by the particle, in definite time interval.

Here, distance travelled by person is

➞ 9 + 5

➞ 14m

➞ Displacement - is change in Position of particles from initial to final point.

Let , x is the displacement of person

Answer :

Distance travelled by person is 14m

Displacement travelled by person is 10.29m

Extra Info.

Displacement is scalar quantity while displacement is vector quantity

Distance depends on path while displacement is independent of path

For a Moving body , distance cannot have zero or negative value but displacement may be positive , negative or zero

Answer 2

Distance covered by her is 15 m and the displacement is 5 m.

Hope it helps.
