Oscillations
AP Physics 1 • Unit 95-8%
The physics of periodic motion, from pendulums to springs. Simple harmonic motion appears throughout physics and provides the foundation for understanding waves.
Core Concepts
- Simple harmonic motion – restoring force ∝ displacement
- Period and frequency – T = 1/f for oscillations
- Mass-spring systems – T = 2π√(m/k) with vertical spring setups
- Simple pendulums – T = 2π√(L/g) and tension analysis
- Energy in SHM – KE ↔ PE exchange with conservative work
- Amplitude independence – why T doesn't depend on A
Key Equations
Real-World Applications
- →Clock pendulums and timekeeping – conical motion
- →Vehicle suspension systems
- →Seismometers for earthquakes
- →Musical instruments
