Fundamental Quantities & Dimensions #shorts

Every measurement needs a unit — but where do those units come from?
In this short, we explore the idea of fundamental quantities in physics: length, mass, and time.
You’ll also learn what dimensions are and how they help us classify physical quantities.
Using velocity as an example, we see how complex quantities are built from simple ones.
This sets the stage for a bigger question:
How many fundamental quantities does physics really need, and why those?
That’s what we’ll uncover in the next video.
