Hooke’s Law
Reference from the original Physics I textbook.
- Hooke’s Law
Within its linear elastic range, an ideal spring exerts a restoring force Fₓ = −kx, where x is displacement from its relaxed length and k is its spring constant in N/m.

Hooke’s law
Hooke’s law models an ideal spring force as proportional to deformation and opposite in direction. The deformation is measured from the spring’s relaxed length, and the law applies only within the spring’s approximately elastic linear range. For example, doubling a small extension doubles the restoring-force magnitude of a spring that obeys this law.
