A) What is the difference between a scalar and a vector quantity, and how are they measured?

S.No

Scalar

Vector

1

Scalar quantities have magnitude or size only.

Vector quantities have both magnitude and direction.

2

It is known that every scalar exists in one dimension only. 

Vector quantities can exist in one, two, or three-dimension.

3

Whenever there is a change in a scalar quantity, can correspond to a change in its magnitude also.

Any change in a vector quantity can correspond to cha change in either its magnitude or direction or both.

4

These quantities can not be resolved into their components.

These quantities can be resolved into their components, using the sine or cosine of the adjacent angle.

5

Any mathematical process that involves more than two scalar quantities will only give scalars.

Mathematical operations on two or more vectors can provide either a scalar or a vector as a result. For instance, the dot product of two vectors only produces a scalar, whereas the cross product, sum, or subtraction of two vectors gives a vector.

Some examples of Scalar quantities are:

<!-- [if !supportLists]-->·         <!--[endif]-->Mass

<!-- [if !supportLists]-->·         <!--[endif]-->Speed

<!-- [if !supportLists]-->·         <!--[endif]-->Distance

<!-- [if !supportLists]-->·         <!--[endif]-->Time

<!-- [if !supportLists]-->·         <!--[endif]-->Area

<!-- [if !supportLists]-->·         <!--[endif]-->Volume

Some examples of Vector quantities are:

<!-- [if !supportLists]-->·         <!--[endif]-->Velocity

<!-- [if !supportLists]-->·         <!--[endif]-->Force

<!-- [if !supportLists]-->·         <!--[endif]-->Pressure

<!-- [if !supportLists]-->·         <!--[endif]-->Displacement

<!-- [if !supportLists]-->·         <!--[endif]-->Acceleration

B) How do you measure distance, displacement, and speed, and what are the units used for each quantity?

1) The formula to calculate the distance (d) is equal to Speed × time. – Unit is meter (m)

2) The formula to calculate the Displacement (s) is equal to Velocity × time - Unit is meter (m)

3) The formula to calculate the Velocity (v) is equal to Distance / time - Unit is meter (m/s)
