Edexcel A Level Physics:复习笔记13.11 Damping & Plastic Deformation
Damping & Plastic Deformation Damping an oscillator affects its amplitude of oscillation: When damping is increased the amplitude decreased damping and amplitude are inversely proportional to e...
Edexcel A Level Physics:复习笔记13.10 Resonance Graphs
Resonance Graphs A graph of driving frequency f against amplitude A of oscillations is called a resonance curve. It has the following key features: When f < f0, the amplitude of oscillations inc...
Edexcel A Level Physics:复习笔记13.9 Free & Forced Oscillations
Free & Forced Oscillations Free Oscillations Free oscillations occur when there is no transfer of energy to or from the surroundings This happens when an oscillating system is displaced and the...
Edexcel A Level Physics:复习笔记13.8 Damped & Undamped Oscillating Systems
Damped & Undamped Oscillating Systems In practice, all oscillators eventually stop oscillating Their amplitudes decrease rapidly, or gradually This happens due to resistive forces, such ...
