- Define elastic and non-elastic deformation in materials.
- Calculate the extension (or compression) of a material using its length and original length.
- State Hooke’s law and use it to calculate the force required to cause a given extension in a spring using the spring constant.
- Describe how elastic potential energy is stored when a material is stretched or compressed by a force.
- Describe force-extension graphs of elastic materials and identify the limit of proportionality.
- Compare the behaviour of different materials before and after the limit of proportionality.
