Q

explain the relationship between the force applied and the extension of an elastic object

A

the extension is directly proportional to the force applied, provided that the limit of proportionality is not exceeded

Q

what is meant by an inelastic (plastic) deformation

A
  • a deformation which results in the object being permanently stretched
  • the object doesn’t return to its original shape when the force is removed
