Length time , mass are known as physical quantities why?

Length, time, and mass are known as physical quantities because they are fundamental properties of objects and can be measured and quantified. These quantities are used to describe and characterize the physical world and are essential for understanding and predicting the behavior of objects and systems in the natural world. Additionally, these quantities are used in various scientific disciplines, such as physics, engineering, and chemistry, to make calculations, analyze data, and formulate theories.

Length, time, and mass are known as physical quantities because they are measurable properties of an object or system. They are fundamental quantities and are not defined in terms of other quantities.

- Length is a measure of the physical distance between two points. It is typically measured in meters (m) or kilometers (km).
- Time is a measure of the duration of an event or the interval between two events. It is typically measured in seconds (s) or hours (h).
- Mass is a measure of the amount of matter in an object. It is typically measured in kilograms (kg) or grams (g).
