Words and meanings to learn
extension
the increase in length of a spring or elastic material when a force is applied to it
limit of proportionality
is the maximum point at which a material, such as a spring, follows Hooke’s Law, meaning that its extension is directly proportional to the applied force
spring constant
amount of force needed to extend or compress a spring by a certain distance
elastic potential energy
is the energy stored in an elastic object, like a spring, when it is stretched or compressed within its elastic limit
compression
refers to the reduction in length of a spring or elastic material when a force is applied to it in the opposite direction (pushing instead of pulling)
