Oscillations

HideShow resource information
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
