===About Hooke's Law===
: '''Hooke's Law''' describes how [[elastic]] [[object]]s behave when a pair of opposing [[force]]s is , one at each end of the [[object]], are applied.
: '''Hooke's Law''' is described by the equation: Force = Spring Constant x Extension

: [[Elastic]] [[object]]s have an [[Elastic Limit]]. This means if the [[force]] is too big they stop obeying '''Hooke's Law''' and start to [[Deformation|deform]] [[Plastic (Property)|plastically]] so they will not return to their original shape.
===Equation===
<math> F = kx </math>
<math> F = k \times x </math>
Where:
: <math>F</math> = Force applied
: <math>k</math> = Spring Constant (stiffness of the elastic object)
: <math>x</math> = Extension of the object
==Key Stage 4==
===Meaning===
'''Hooke's Law''' states that the [[extension]] of an [[elastic]] [[object]] [[Directly Proportional|directly proportional]] to the [[force]] applied to the [[object]].
===About Hooke's Law===
: '''Hooke's Law''' describes how [[elastic]] [[object]]s behave when a pair of [[Equilibrium Forces|equilibrium forces]] is applied.
: '''Hooke's Law''' is described by the equation: Force = (Spring Constant) x (Extension)
: '''Hooke's Law''' applies to an [[object]] until it reaches its [[Elastic Limit|elastic limit]], at which point the [[object]] begins to behave [[Inelastic Deformation|plastically]].
