1249 - What are the derived physical quantities calculated from basic physical quantities like time, length, and mass

Derived physical quantities are values we get by combining basic physical quantities like time, length, and mass. Here are some examples:

1. Speed (Length/Time): It tells us how fast something is moving (e.g., 50 km/hour).
2. Acceleration (Length/Time²): It tells us how quickly speed changes (e.g., increasing from 0 to 100 km/hour).
3. Area (Length × Length): It's the size of a flat surface (e.g., a piece of paper or a room).
4. Volume (Length × Length × Length): It's the amount of space inside something (e.g., a box or a pool).
5. Density (Mass/Volume): It tells us how tightly packed something is (e.g., gold vs. wood).
6. Pressure (Force/Area): It's the force on something per unit area (e.g., air pressure on the Earth).
7. Force (Mass × Acceleration): It's the push or pull on an object (e.g., throwing a ball).
8. Energy (Mass × Speed² or other forms): It's the ability to do work or make something happen.

These are just a few examples of derived physical quantities.
