The two physical quantities of measurement are:
1. Scalars - quantities with magnitude (size) only
examples:
distance - 1 km
mass - 5kg
speed - 80km/h
2. Vectores - quantities having both magnitude and direction
examples:
displacement - 1km, to the right
weight - 50 newtons
velocity - 80km/h, west

What is meant by unit of a physical quantity?
the seven basic physical quantities ;lenght, mass,time temperature,electric currrent ,luminous intensity and amount ofsubstance which areindependent of any other quantities for their measurement are clled
Do physical quantities have numerical magnitude and a unit?
Many do. For instance, you would probably agree that your own height and weight are physical quantities. Each of these has a magnitude or size and a unit of measurement. They might be, say, 157 cm and 50 kg.
Types of physical quantities?
Physical Quantities are of TWO types: 1) Fundamental Quantities. 2) Derived Quantities.
What are four fundamental quantities used in measurement?

What is a quantity that can be measured?
Physical quantities are quantities that can be measured. For example: water, distance, etc.

Why isn't one million francium atoms per second not enough to make a basic measurement?
These quantities are too small for the measurement of physical properties.

What are the three fundamental dimensions used in Physics?
Length, mass, and time are the three fundamental dimensions on which the measurement of all physical quantities is dependent.
What are the different quantities of measurement?
different quantities of measurements are Cubic Meters and Kilograms
What are theclassifications of physical quantities according to magnitude and direction?
Physical quantities that need both magnitude and direction for its complete description are known as vector quantities. Physical quantities that need only direction for its complete description are known as scalar quantities.
What are Physical quantities?
They are properties that you can measure and be verified by another party. Usually, standards are available to eliminate any difference in measurement methods and definitions. For example, we can measure length, speed, weight, humidity, temperature, and time, with certainty. Those are physical quantities. Contrarily, we cannot measure inflation rate, hunger, pain, etc. with certainty. In short they are quantities that can be measured.

What is the g for in food measurement?
Quantities with a 'g' after them are measurements in grams.
What is solar quantities?
Scalar quantities are physical quantities that can be described with a single value. They are unlike vector quantities which require both magnitude and direction.
