PhysicsOscillationsA2/A-levelEdexcel Created by: RYANchandlerCreated on: 19-04-18 10:48 Amplitude maximum displacement from mean position / m 1 of 9 Period time taken to complete one single oscillation / s 2 of 9 Frequency number of complete oscillations per second / Hz 3 of 9 Simple harmonic motion periodic motion about an equilibrium point, such that acceleration is: proportional to the displacement, and always directed towards the fixed point 4 of 9 Equation for simple harmonic motion F = -kx 5 of 9 Simple pendulum small, dense pendulum ball with light, inextensible string 6 of 9 When is the kinetic energy of a pendulum at it's minimum? Midpoint of motion, or bottom of swing as velocity is it's highest 7 of 9 Free oscillations no external forces act on the oscillating system, apart from the force that causes it 8 of 9 Damped oscillation Energy is transferred to surroundings, resulting in oscillations being reduced in amplitude and energy 9 of 9
