Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. Here's a taste from this kit; the app has the full deck.
The foundation of all physics.
A physical quantity is any property of a material or system that can be *measured* and expressed in numbers. It has a numerical value and a unit. For example, length, mass, time, and temperature are all physical quantities because they can be quantified.
↳ If it can be measured and given a number with a unit, it's a physical quantity.
The process behind every number.
Measurement is the process of comparing an unknown physical quantity with a known standard quantity of the same kind, called a unit. The result of a measurement is always a number followed by the unit used.
↳ Measurement is a comparison against a fixed, known standard (unit).
The building blocks and their combinations.
Physical quantities are classified into two main types. Fundamental (base) quantities are independent and cannot be defined in terms of other quantities. Derived quantities are obtained by mathematical combinations (multiplication, division) of fundamental quantities.
↳ Fundamental quantities stand alone; derived quantities are built from them.
This topic introduces the concept of physical quantities as measurable properties expressed with a numerical value and a unit. It explains the classification into fundamental and derived quantities, the importance of the...

20 questions laddered from warm-up to topper-level, each with an explanation. A taste:
Which of the following is a fundamental physical quantity?
BeginnerMass
Mass is one of the seven fundamental quantities; speed, force, and area are derived from fundamental quantities.
The SI unit of luminous intensity is:
BeginnerCandela
The candela (cd) is the SI base unit for luminous intensity. Lumen and lux are derived units for luminous flux and illuminance.
Which of the following is a derived unit?
BeginnerNewton
Newton is derived from base units (kg·m/s²). Kilogram, second, and ampere are base units.
The SI unit of amount of substance is:
BeginnerMole
The mole (mol) is the SI base unit for amount of substance.
