Hooke's principle

Hooke's principle states that the force needed to stretch or compress a spring is directly proportional to how much it is stretched or compressed, as long as the deformation is small. In other words, the more you pull or push, the harder the spring pushes back, and this relationship remains linear up to a limit called the elastic limit. This principle helps us understand how materials respond to forces and predicts their behavior when deformed within their elastic range.
