Hooke's Law states that the extension of a spring is directly proportional to the force applied. It can be written as Force = Spring Constant x Extension. Young's Modulus is a material property that indicates how much a material will deform under stress. When stress is applied to a metal, the positive ions will spread apart as the atomic bonds stretch like springs. If the metal is within its elastic limit, it will return to its original shape when the stress is removed.

- 3. Hooke’s Law This is the force applied This is the (N) extension (m)
- 4. We can write it another way This is the This is the extension of This is the gradient (N/m) force applied the spring and is unique (m) (N) for each spring
- 6. Elastic Movement in Metals Atoms are stacked in planes as +ve ions in a sea of -ve free electrons. When stress is applied to the metal, the +ve ions will start to spread apart. The atomic bonds stretch, and the attractive forces between the atoms will oppose the applied stress, like millions of tiny springs. If the metal has not yielded, the interatomic forces will pull the metal back into its original shape when the stress is removed.
