Quantity and Unit
Is it difficult if you go to a shop to buy granulated sugar and say "Mom, buy IDR 10.000 granulated sugar?"
Well, I'm confused, how much sugar will I get for IDR 10.000 Well, that's when this unit comes. Unit is a life savior. How come? Who is the unit? Let's see the explanation bestie :)
In everyday life there are many things that we do not realize that we are studying physics or applying physics concepts. For example, when we walk, boil water, clean up tables and chairs, it's all physics. It's crazy how cool physics is.
Now, we will focus on discussing the quantities and units.
Quantity and Unit
#Principal amount
1. Mass
2. Length
Length has units of meters (m). For example, when measuring the length of the blackboard, the length of the blackboard measured using a meter results in 2 meters.
3. Time
Time is the next basic quantity which has units of seconds (s). For example, Doni ran 100 meters in 48 seconds. The measuring instrument used is a stopwatch.
4. Strong Current
Current strength is measured using an ammeter. While the unit of current strength itself is the ampere (A).
5. Temperature
Temperature is measured using a thermometer and has units of Celsius (C).
6. Light Intensity
This light intensity has units of candela (Cd).
#Derivative Quantity
Derived quantities are quantities that are derived from the base quantity. Or simply a derived quantity is a quantity consisting of 2 or more principal quantities.
Here is an example
The unit speed is m/s, which consists of the principal quantity of length and the principal quantity of time.
For example, just one, don't take too many, the rest, my friends, write it down, try it in the comments column, ehehe
See ya :)

Don't forget to share with other friends, so they both know :).....
