Which of the following sets of quantities is fundamental?
Answer Details
The set of quantities that is fundamental is "length, mass, and time." These quantities are considered fundamental because they are independent and cannot be defined in terms of one another. All other physical quantities can be derived from these fundamental quantities using mathematical equations. For example, speed can be derived as distance over time, and acceleration can be derived as change in speed over time. Therefore, length, mass, and time are considered the three basic building blocks of physics and are used to describe all physical phenomena.
