Hooke's Law, named after the 17th-century British scientist Robert Hooke, is a principle in Physics that provides the relationship between the force applied to a spring and the displacement caused by it. It is an essential concept in the study of Classical Physics and particularly in the field of mechanics. In this tutorial, we'll delve into how to calculate the spring constant - a parameter in Hooke's Law - using factors such as the force applied, the distance from equilibrium, and the spring's equilibrium position.

| Spring Constant (k) = Newton/Meter |
The primary formula given by Hooke's Law to calculate the spring constant (k) is as follows:
Where:
To find the spring constant, you can rearrange the formula to:
This formula is attributed to Robert Hooke, who first stated the law as a Latin anagram in 1660 and then published the solution in 1678. Although the law applies specifically to springs, it has been extended and applied in various fields of science and engineering, such as the study of materials (material science), molecules in chemistry, and even in describing the behaviour of celestial bodies in astrophysics.
Hooke's Law is integral to many everyday applications. For instance, vehicle suspension systems use the principle of Hooke's Law to absorb shocks. In addition, engineers use it to design spring-loaded mechanisms in various devices, like retractable pens, doors, and even in trampolines.
Robert Hooke is undoubtedly the key individual when discussing Hooke's Law and the spring constant. His work and findings laid a significant foundation in the field of mechanics, and his studies of elasticity have played a critical role in the design and manufacture of numerous mechanical systems.
Understanding Hooke's Law and the spring constant is integral to a broad range of scientific and engineering fields. This principle underlies many of the technologies and infrastructures we rely on daily. From the suspension in your car to the retractable pen you write with, the impact of Hooke's Law is both profound and pervasive.
