Ohm's Law :

Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperatures remain constant. In the equation, the constant of proportionality, R, is called Resistance and has units of ohms, with the symbol Ω.

Hooke's Law Spring Constant

Hooke's law, law of elasticity discovered by the English scientist Robert Hooke in 1660, which states that, for relatively small deformations of an object, the displacement or size of the deformation is directly proportional to the deforming force or load.
