Hooke's law
Hooke's Law is a principle of Physics that states that the force (F) needed to extend or compress a spring by some distance (x) is proportional to that distance. That is: F = kx, where k is a constant factor characteristic of the spring (its stiffness), x is the distance stretched, and F is the force applied.
Pronunciation
Hooke's Law is pronounced as /hʊks lɔː/.
Etymology
Hooke's Law is named after the 17th-century British physicist Robert Hooke who first stated the law in 1676.
