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 definition of physical quantities?

Physical quantities are properties or attributes of phenomena that can be measured and expressed numerically. These quantities represent aspects of the physical world, such as length, mass, time, and temperature, and are typically described by a numerical value and a unit of measurement. Physical quantities form the basis of scientific measurement and analysis.


What is a foundamental quantity?

A fundamental quantity is a physical quantity that is independent and not defined in terms of other physical quantities. These fundamental quantities form the basis for the measurement of other physical quantities. Examples of fundamental quantities include mass, length, time, and electric charge.


What is the scale definition in physics and how does it relate to the measurement of physical quantities?

In physics, scale refers to the ratio between the size of an object in the real world and its representation in a measurement. It is used to accurately measure physical quantities by providing a standard reference point for comparison.


What requirements must be met by two physical quantities when they are added together?

When two physical quantities are added together, they must have the same units in order to be combined. This means that both quantities must be expressed in the same type of measurement, such as meters or kilograms, for the addition to be valid.


What is the quantities of measurement?

Quantities of measurement refer to the different units used to quantify physical attributes such as length, mass, time, and volume. Examples include meters for length, kilograms for mass, seconds for time, and liters for volume. These units help standardize measurements and facilitate accurate communication of quantities.

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.


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 base quantities and derived quantities?

Base quantities are fundamental physical quantities that cannot be defined in terms of other physical quantities. They are used as building blocks in expressing other physical quantities. Derived quantities, on the other hand, are physical quantities that are derived from combinations of base quantities through multiplication and division with or without other derived quantities.


What are basic quantities and derived quantities?

Basic quantities are physical quantities that are independent and cannot be defined in terms of other physical quantities, such as length, time, and mass. Derived quantities, on the other hand, are physical quantities that are defined in terms of one or more basic quantities, such as speed, acceleration, and force.


Types of physical quantities?

Physical quantities can be broadly categorized as scalar or vector quantities. Scalar quantities have only magnitude, like mass or temperature, while vector quantities have both magnitude and direction, like velocity or force. Other types of physical quantities include derived quantities (obtained from combinations of base quantities) and dimensionless quantities (without units).


What is meant by joint measurement?

Joint measurement refers to the simultaneous measurement of multiple properties or variables of a system. It involves determining the values of these properties together in a single measurement process. In quantum mechanics, joint measurements can reveal correlations between different physical quantities of a system.
