understand that the condition for simple harmonic motion is $F = −kx$, and hence understand how to identify situations in which simple harmonic motion will occur

be able to use the equations $a = −ω^2x$, $x = A\cos{ωt}$, $v = −Aω\sin{ωt}$, $a = −Aω^2\cos{ωt}$, and $T = \dfrac{1}{f} = \dfrac{2π}{ω}$ and $ω= 2πf$ as applied to a simple harmonic oscillator

be able to use equations for a simple harmonic oscillator $T = 2π\sqrt{\dfrac{m}{k}}$, and a simple pendulum $T = 2π\sqrt{\dfrac{l}{g}}$

be able to draw and interpret a displacement–time graph for an object oscillating and know that the gradient at a point gives the velocity at that point

be able to draw and interpret a velocity–time graph for an oscillating object and know that the gradient at a point gives the acceleration at that point

understand what is meant by resonance

CORE PRACTICAL 16: Determine the value of an unknown mass using the resonant frequencies of the oscillation of known masses.

understand how to apply conservation of energy to damped and undamped oscillating systems

understand the distinction between free and forced oscillations

understand how the amplitude of a forced oscillation changes at and around the natural frequency of a system and know, qualitatively, how damping affects resonance

understand how damping and the plastic deformation of ductile materials reduce the amplitude of oscillation.
