Question

A displacement vector is a
a) Change in position
b) Velocity
c) Scalar
d) Distance without directions ​

Answer 1

Displacement vector is a :

$\boxed{\sf{\large{Change\:in \:position}}}$

First of all , What is a vector ?

• Vector is a physical quantity represented by both magnitude and direction.

How is vector different from scalar quantity?

• Scalar quantities have only magnitude and no direction, where as vectors have both.

Displacement Vector:

• Let us say that w.r.t to the origin , an object changed his position from x1 to x2

• Displacement Vector will be

$\boxed{ \sf{ \vec{d} = (x2 - x1) \: \hat{i}}}$

• Here (x2 - x1) denotes the magnitude where as $\hat{i}$ denotes the direction.

This means that displacement vector is a change in position.

Vector

Vector is a physical quantity represented by magnitude and direction both.

Displacement Vector:

Displacement Vector will be :-

$</p><p>\boxed{ \sf{ \vec{d} = (x2 - x1) \: \hat{i}}} </p><p>d</p><p> =(x2−x1) </p><p>i</p><p>$

Here (x2 - x1) denotes the magnitude where as î denotes the direction.

Change in position.
