Words and meanings to learn
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
extension
the increase in length of a material or object when a force is applied to it
limit of proportionality
the point beyond which Hooke’s Law is no longer obeyed
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
