You’re practicing an instrument and can’t seem to figure out how to play a song. You break it up scientifically, you know how to play the notes and chords. Then you simply need to put them together in a specific way to understand the song right? In its most basic form this is true, but to truly perform the song, you must develop an understand the specific conditions of each chord whether that is octave or pitch. But when you are done analyzing all of the parts you should be able to put them together into the beauty of a song.
Notice how in this story you need to learn how to play a song. You know the individual parts of the song, but don’t know how to put them together.Once you do however, it becomes easier and makes sense. Similarly, derived units are units that you use other units to find.
Derived Units are for examples,
Area=length x width
Volume= length x width x height
By finding some easy to locate things, you can use them to derive more advanced units.
What is the area of a square that has a length of 3 and the width of 7?
What is the density of a solution with a mass of 3 grams and 12 L volume?
What is another example of a derived unit?
