What does Hooke's Law state?

The force needed to extend or compress a spring by some distance is proportional to that distance (F = -kx).

What is the spring constant k?

It is a measure of the stiffness of the spring. A higher k means a stiffer spring.

What is Elastic Potential Energy?

It is the energy stored in the spring when it is deformed (stretched or compressed).
