Simple Harmonic MotionSign up

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 = -omega^2 x, x = A cos(omega t), v = -A omega sin(omega t), a = -A omega^2 cos(omega t), and T = 1/f = 2 pi / omega and omega = 2 pi f as applied to a simple harmonic oscillator · be able to use equations for a simple harmonic oscillator T = 2 pi sqrt(m/k), and a simple pendulum T = 2 pi sqrt(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

Resonance and DampingSign up

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.
