Words and meanings to learn
Hooke's Law
states that the extension of a spring (or other elastic object) is directly proportional to the force applied to it, provided the limit of proportionality is not exceeded
extension
the increase in length of a material or object when a force is applied to it
elastic
a material or object’s ability to return to its original shape after the force causing its deformation is removed
inelastic
a material or object that does not return to its original shape or size after the force causing deformation is removed
limit of proportionality
the point beyond which Hooke’s Law is no longer obeyed
