Length is fundamental because space is fundamental and relates two other fundamental units energy and force.
I suppose you mean "inertia". That is the tendency of an object to remain at rest if it is resting, or to keep moving (at a constant velocity) if it is moving.
Science describes more than two fundamental forms of energy, but perhaps you are thinking of kinetic energy and potential energy. Heat is also a form of energy, as are chemical energy, nuclear energy, electromagnetic energy, etc.
It is the Law of Conservation of Energy, aka the First Law of Thermodynamics.The concept of energy is one of the most fundamental concepts of science.This is the first law of thermodynamics and it is worth saying in several ways.(A) Energy is conserved.(That is short and accurate answer but non-scientists are not used to the word "conserved" being used in this way. But, scientists use it to mean "Stays the same" all the time.)(B) Energy can change from one form of energy to another, but energy can not be created or destroyed.(This is a fundamental law of Nature and the first law of thermodynamics, that energy of a closed system can never change. Sometimes it is said that "the total energy of the universe is always the same." )Discussion:Nature provides us with the Law of Conservation of Energy, whichever way you want to say it. It was about 400 years ago that science started to understand energy. At first it was only kinetic energy, the energy of motion, that was observed unchanged.Soon this was expanded to include gravitational potential energy. Later this expanded to other forms such as elastic potential energy, heat energy, chemical energy, nuclear energy, electrical and many other forms, including the famous "mass energy," E=mc2.How grand to know that the first law of thermodynamics says that we will never run out of energy. Alas, the second law says that Entropy is the problem and energy cannot always be used to do work.Aside: There is a big discussion in cosmology now about "dark energy." This should not be confused with the possibility that maybe energy is not conserved. The truth is that cosmologists have no idea what this "dark energy" is and it is not even a sure thing that it is energy.)
Law of conservation of energy. Energy can't be created or destroyed is the basic statement of the law of conservation of energy.
Novanet:Energy can be transferred but cannot be destroyed.
a fundamental law is but constitutional law
No. Energy is never created or destroyed. The Law of Conservation of Energy is one of the fundamental bricks in science.
Coulomb's law is not a fundamental law because it applies only to point charges.
a fundamental law is but constitutional law
Fundamental law is the law determining the constitution of the government of a state, while statutory law is the body of laws created by legislative statutes.
Length is fundamental because space is fundamental and relates two other fundamental units energy and force.
