Question

A body moves 10m from A to B and returns break from B to A. Total distance and total displacement in this case respectively are.
a. 20m, 20m
b. 0m, 0m
c. 0m, 20m
d. 20m, 0m​

Answer 1

Answer:

Total distance =10m+10m

=20m

Total displacement =10m-10m

=0

Therefore, option C is the correct answer

Answer 2

Given,

The body moves 10 metres from A to B.

Then it backs from B to A by moving the same distance.

To find,

The total covered distance and total displacement of that body.

Solution,

We can easily calculate the total covered distance, by adding the distance of the going trip and return trip.

Total distance = (10+10) = 20 metres

Now, the total displacement is the distance between the starting point and the end point of a journey. Here, the starting point and wnd point are exactly same and that's why, the displacement will be zero.

Displacement = (10-10) = 0 metre

Hence, the total covered distance is 20 metres and total displacement is 0 metre. (option d)
