- Periodic motion: Periodic motion refers to any motion that repeats itself after a certain interval of time.
- [Simple harmonic motion (SHM)](/ap-physics-c-mechanics/key-terms/simple-harmonic-motion-shm): SHM is a type of periodic motion where the restoring force acting on an object is directly proportional to its displacement from equilibrium.
- Oscillation: Oscillation refers to repetitive back-and-forth movement around an equilibrium position.
