Fundamental Physical Quantities

Fundamental physical quantities are basic measurements that are used to describe the physical properties of matter and energy. They are the building blocks of all other physical quantities, and their standard units are used as a reference for all other measurements.

Example:

Here are a few Example of fundamental physical quantities and their standard units:

Length: The measurement of the platinum-iridium distance between two points. The standard unit for length is the metre (m).
Mass: The measurement of the amount of matter in an object. The standard unit for mass is the kilogram (kg).
Time: The measurement of the duration of an event. The standard unit for time is the second (s).

Derived Quantities

Derived quantities are quantities that can be calculated from other quantities using mathematical operations.

Example:

Speed:

Speed is a derived quantity because it can be calculated by dividing distance by time (speed = distance/time).

Acceleration:

Acceleration is calculated by dividing the change in velocity by the change in time (acceleration = change in speed/time).

Force:

Force is calculated by multiplying the mass by acceleration (force = mass x acceleration).
