understand and use the terms displacement, amplitude, period, frequency, angular frequency and phase difference in the context of oscillations, and express the period in terms of both frequency and angular frequency
understand that simple harmonic motion occurs when acceleration is proportional to displacement from a fixed point and in the opposite direction
use a = –ω2 x and recall and use, as a solution to this equation, x = x0 sin ωt
use the equations v = v0 cos ωt and v = ±ω ( )
analyse and interpret graphical representations of the variations of displacement, velocity and acceleration for simple harmonic motion
17.2 Energy in simple harmonic motion
describe the interchange between kinetic and potential energy during simple harmonic motion
recall and use E = 1/2mω2 x0 2 for the total energy of a system undergoing simple harmonic motion
17.3 Damped and forced oscillations, resonance
understand that a resistive force acting on an oscillating system causes damping
understand and use the terms light, critical and heavy damping and sketch displacement–time graphs illustrating these types of damping
understand that resonance involves a maximum amplitude of oscillations and that this occurs when an oscillating system is forced to oscillate at its natural frequency
