Vector and Scalar Quantities
Assume that a gold bar is hidden in a room where you are standing. The
following information are also given:
It is underneath the sofa 2 meters away from you.
а.
b.
It is 2 meters away from where you are standing.
с.
It is 2 meters north from where you are standing.
Which of the given information would be most useful? Which is the least
useful? Let us analyze each of the given.
You will have to search the whole area of the sofa starting with a
distance of 2 meters.
а.
You will have to search all points 2 meters away from you including
b.
those above and below the sofa.
C.
Provided that you know where the direction of north, you will be able
to find the gold bar quickly.
Among the choices, letter c has a specified direction and important
information.
Physical quantities are classified into two: vector and scalar quantities.
Vector is a physical quantity that has both magnitude and direction.
Examples of vector quantities are the following: displacement of 2.0 m [North],
velocity of 60 km/h [East), and force of 40 Newton [West).
Scalar is a physical quantity that has only magnitude. Examples of scalar
quantities are the following: speed of 60 km/h, time of 3 hours, and temperature
of 28°C.
