Physical law. A physical law, scientific law, or a law of nature is a scientific generalization based on empirical observations of physical behavior. Empirical laws are typically conclusions based on repeated scientific experiments over many years, and which have become accepted universally within the scientific community.

Physical law. A pheesical law or scienteefic law, accordin tae the Oxford Inglis dictionar, (translatit tae Scots) "is a theoretical principle deduced frae particular facts, applicable tae a defined group or class o phenomena, an expressible bi the statement that a pairticular phenomenon always occurs if certain condeetions be present."

Hooke's law is a law of physics that states that the force ( F) needed to extend or compress a spring by some distance ( x) scales linearly with respect to that distance—that is, Fs = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness ), and x is small compared to the total possible deformation of the spring.

Law is a system of rules created and enforced through social or governmental institutions to regulate behavior, [2] with its precise definition a matter of longstanding debate. [3] [4] [5] It has been variously described as a science [6] [7] and the art of justice. [8] [9] [10] State-enforced laws can be made by a group legislature or by a single legislator, resulting in statutes; by the ...

Wien's displacement law (eqn [1]) relates the wavelength of radiated energy to temperature. [1] λ = 2897 T. In eqn [1], λ is the wavelength (in μm) and T is the temperature in K. Wien's law can be used to show that most terrestrial surfaces emit radiation of 8–12 μm, with most growing plants radiating at about 10 μm.
