About Eduqas A Level Physics 1.6 Vibrations
This topic covers oscillations.
What you need to know
- SHM a = −ω²x; displacement x = A cos ωt.
- Systems Mass-spring T = 2π√(m/k) and pendulum T = 2π√(l/g).
- Energy Exchange between kinetic and potential energy.
- Damping and resonance Light, critical and heavy damping; resonance at the natural frequency.
Common mistakes in 1.6 Vibrations
- Saying acceleration is maximum at equilibrium.
- Forgetting the negative sign.
- Confusing forced and natural frequency.
