Final answer:
Physics defines fundamental physical quantities and their units, with a focus on length, mass, time, and more, all of which serve as the basis for measuring other physical quantities.
Explanation:
Fundamental Physical Quantities in Physics
In physics, there are seven fundamental physical quantities: length, mass, time, electric current, temperature, amount of substance, and luminous intensity. These fundamental quantities are measured in base units like meters, kilograms, seconds, amperes, kelvins, moles, and candelas. All other physical quantities are derived from these fundamentals through mathematical combinations.
Example:
Speed, a derived quantity, is the ratio of length to time.
