Candidates should be able to:
- use Hooke’s law as a model relating the force in an elastic string or spring to the extension or compression, and understand the term modulus of elasticity
- use the formula for the elastic potential energy stored in a string or spring (Proof of the formula is not required.)
- solve problems involving forces due to elastic strings or springs, including those where considerations of work and energy are needed. (e.g. a particle moving horizontally or vertically or on an inclined plane while attached to one or more strings or springs, or a particle attached to an elastic string acting as a ‘conical pendulum’.)
