Question

For one dimensional motion, we often choose the x–axis as the line along which the motion takes
place. Then the position of an object at any moment is given by its x- coordinates. If the motion is
vertical, as for a dropped object, we usually use y–axis. We need to make distinction between the
distance an object has travelled and its displacement.
In context of above lines, answer the following questions:
The below figure represents walking of person 70 m east, then 30 m west.

Q1.1 Choose the most appropriate answer for person displacement and total distance for the
journey, he covered
a) 100m, 100m
b) 40m, 40m
c) 70m, 40m
d) 40m, 100m

Answer 1

Answer:

Unit 1: Distance & Displacement Q1For one dimensional motion, we often choose the x–axis as the line along which the motion takes place. Then the position of an object at any moment is given by its x- coordinates. If the motion is vertical, as for a dropped object, we usually use y–axis.

Answer 2

Explanation:

$\displaystyle{\implies\underline{\boxed{\red{\sf\:correct \: answer\:=\:70m \: and \: 40m \: }}}}⟹</p><p>$
