S2.9 Linear restoring force
- A stretched or compressed spring exerts a force on a body to which it is attached.
- The magnitude of the force is proportional to the distortion of the spring x provided x is small (Hooke’s Law).
|
- Equation of motion of such a body is
- This is the generic equation of simple harmonic motion (SHM).
- Forward reference: S6.
