Free vibration and forced vibration
Free vibration and forced vibration
When an oscillating system is displaced and released, it vibrates at its natural frequency f0f_0f0. Frequency is measured in hertz, Hz\text{Hz}Hz, which means oscillations per second.
Step-by-step lessons on AQA A Level Physics Forced vibrations and resonance (A-level only). Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
