In physics, a spring constant refers to the stiffness of a spring, which determines the relationship between the force applied to the spring and the resulting displacement or deformation. It is a measure of how strongly the spring resists being stretched or compressed.
Understanding the spring constant is crucial for various applications, such as designing and analyzing springs, shock absorbers, and other mechanical systems involving springs. Knowledge of the spring constant allows engineers and scientists to predict the behavior of a spring under different load conditions.
