How are force and extension related?
Force and extension are related through Hooke's Law, which states that the force needed to stretch or compress a spring is directly proportional to the extension or compression of the spring. This means that the more force applied, the greater the extension (or compression) of the spring, and vice versa. Mathematically, this relationship can be expressed as F = kx, where F is the force, k is the spring constant, and x is the extension (or compression) of the spring.
