Spring Constant
Definition
The spring constant represents how stiff or flexible a spring is. It determines how much force will be required to stretch or compress a spring by a certain distance.
Analogy
Imagine stretching out different rubber bands - one thin and one thick. The thicker rubber band would have a higher spring constant because it requires more force to stretch it compared to the thinner one.

Hooke's Law: Hooke's Law states that the force exerted by a spring is directly proportional to the displacement of the spring from its equilibrium position.
Elastic Potential Energy: Elastic potential energy is the energy stored in an object when it is stretched or compressed, such as a spring.
Equilibrium Position: The equilibrium position of a spring is where there is no net force acting on it and it remains at rest.
