Springs, elasticity and the force-extension practical
Elastic and inelastic deformation, F = ke and the limit of proportionality, elastic potential energy ½ke², and the required practical on a spring.
You will be able to
- Tell elastic from inelastic deformation
- Use F = ke with extensions in cm or m
- Find k from a force-extension graph and spot the limit of proportionality
- Use E = ½ke²
- Plan and analyse the spring practical
25 minutes, 10 exam-style questions, with the Mass on a spring simulation.
