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 the significance of the dimension of physical quantities in the field of physics?

The dimension of physical quantities in physics is significant because it helps in understanding and analyzing the relationships between different physical quantities. By assigning dimensions to quantities such as length, time, mass, and others, physicists can create equations that accurately describe the behavior of natural phenomena. This allows for precise measurements, calculations, and predictions in various scientific fields.


What system is used to make all scientific measurements?

The metric system is used to make all scientific measurements. It provides a standard set of units for measuring length, mass, volume, temperature, and other quantities.


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.
