Key terms in this lesson
- Hooke's law
- The extension of a spring or wire is directly proportional to the force applied, provided the limit of proportionality is not exceeded.
- Spring constant
- The force per unit extension needed to stretch a spring, equal to the gradient of a force-extension graph while Hooke's law is obeyed.
