Hooke's Law is a physical principle that describes the relationship between the force applied to an object and the resulting extension or compression of the object.
Hooke's Law was discovered by English scientist Robert Hooke in the 17th century.
The formula for Hooke's Law is F = -kx, where F is the force applied, k is the spring constant, and x is the displacement of the object from its equilibrium position.
Hooke's Law is only applicable to elastic materials, meaning materials that can return to their original shape after being deformed. It also assumes that the force applied is directly proportional to the displacement of the object, which may not always be true.
Hooke's Law is important because it helps us understand and predict the behavior of elastic materials under different forces. It is also the basis for many engineering applications, such as designing springs and shock absorbers.
