Hukov zakon definiše elastične deformacije tela.
Zakon tvrdi da je deformacija tela proporcionalna intenzitetu deformišuće sile, pod uslovm da se ne pređe granica elastičnosti tela. Ukoliko granica elastičnosti nije premašena telo će se vratiti u prvobitni položaj kada se sila ukloni. Zakon je otkrio Robert Huk 1676 godine.

Množina reči Hooke's law je Hooke's laws.
Defines the basis for the measurement of mechanical stresses via the strain measurement. The gradient of Hooke’s line is defined by the ratio of which is equivalent to the Modulus of Elasticity E (Young’s Modulus).
Stress is proportional to strain in the elastic range. The value of the stress at which a material ceases to obey Hooke`s law is known as the elastic limit.
Law stating that the deformation of a body is proportional to the magnitude of the deforming force, provided that the body's elastic limit (see elasticity) is not exceeded. If the elastic limit is not reached, the body will return to its original size once the force is removed. The law was discovered by Robert Hooke 1676.
For example, if a spring is stretched by 2 cm by a weight of 1 N, it will be stretched by 4 cm by a weight of 2 N, etc.; however, once the load exceeds the elastic limit for the spring, Hooke's law will no longer be obeyed and each successive increase in weight will result in a greater extension until finally the spring breaks.
