Question

Person travels a
distance of 18 km
towards east and returns along the same path
and travels for 5km. Find distance covered
by him and displacement produced by him.
​

Answer 1

Answer:

When a person travels 18km towards east and then returns back 5km in the same path , then his displacement will be equal to the shortest distance between initial and final point . In this case since the person returns back 5km , so the displacement produced by him will be ( 18km - 5km ) = 13km .

But if distance travelled was asked then it will be equal to the total path covered by the man , irrespective of dirⁿ of motion .

Displacement is a vector quantity.

It is equal to the shortest distance between final and initial points.

Displacement is always equal to or less than distance.

Velocity equals to displacement covered per unit time.

It can be calculated using vector law of addition.
