** Physical quantities** are fundamental concepts in physics that can be measured or quantified. They provide a way to describe the properties of the physical world in a precise and standardized manner. These quantities can be categorized into two types:

: Scalar quantities have only magnitude and no direction. Examples include**Scalar Quantities**,**mass**, and**temperature**. When you measure them, you get a numerical value with a unit, like 5 kg or 25Â°C.**time**: Vector quantities have both magnitude and direction. Examples include**Vector Quantities**,**velocity**, and**force**. When you measure vector quantities, you get a numerical value along with a unit and a specific direction, such as 20 m/s east or 10 N north.**displacement**

Physical quantities serve as the foundation for scientific measurements and calculations, allowing scientists and engineers to understand and manipulate the physical world effectively.
