1

Define oscillations

o An oscillation is any motion in which the displacement of a particle from a fixed point keeps changing direction and there is a periodicity in the motion i.e. the motion repeats in some way.

2

Define displacement

o displacement (x) – distance from the equilibrium or zero point

3

Define amplitude

o amplitude (x0) – maximum displacement from the equilibrium or zero point

4

Define frequency

o frequency (f) – How many oscillations are completed in one second, equal to the inverse of the period

5

Define period

o period (T) – time it takes to complete one oscillation and return to starting point

6

Define phase difference

o phase (�) – the difference between the actual position of a sine wave at t=0 and zero. The value of � determines the displacement at t=0
