  {"name":"Hooke's Law","description":r"""
Force exerted by a spring is proportional to its displacement (linear region).

$$F = -kx$$

Where:
- $F$: Restoring force (Newtons)
- $k$: Spring constant (N/m)
- $x$: Displacement from equilibrium (meters)

The negative sign indicates the force opposes displacement.
