Question

What is the unit of $K$ in Hooke's Law?

Answer 1

Hooke's Law

1. Hooke's law states that the restoring force acting on the material is directly proportional to the change in the length of the material.
2. Hooke's Law can be stated mathematically as $F=-kx$.
3. Here, $F=$applied force, $k$ is a spring constant, and $x$ is the displacement or change in the length.
4. Many materials obey this law as long as the load does not exceed the elastic limit of the material.
5. The rate of stiffness of the material is often known as the spring constant, $k$.
6. The SI unit of $K$ is $\mathrm{newton}\mathrm{per}\mathrm{meter}(\mathrm{N}/\mathrm{m})\mathrm{or}\mathrm{kilogram}\mathrm{per}\mathrm{second}\mathrm{squared}(\mathrm{kg}/{\mathrm{s}}^2)$.
