The ‘valentine
vector’ says,
“I was only
a scalar
until you
came along
and gave me
direction.”
What is your
scientific insight
in this statement?
What Is Scalar Quantity?
Scalar quantity is defined as
The physical quantity with magnitude and no direction.
Some physical quantities can be described just by their numerical value (with their respective units) without directions (they don’t have any direction). The addition of these physical quantities follows the simple rules of the algebra. That is only their magnitudes are added.
What is Scalar quantity example?
There are plenty of scalar quantity examples, some of the common
examples are:
Mass
Speed
Distance
Time
Area
Volume
Density
Temperature
What Is Vector Quantity?
A vector quantity is defined as
The physical quantity that has both direction as well as
magnitude.
A vector with the value of magnitude equal to one and direction is called unit vector represented by a lowercase alphabet with a “hat” circumflex. That is “û“.
What are some examples of vector quantities?
Vector quantity examples are many, some of them are given
below:
Linear momentum
Acceleration
Displacement
Momentum
Angular velocity
Force
Electric field
Polarization
