1.1 Amplitude: max displacement from
equilib position
1.2 Period: time for one
complete oscillation
1.3 Phase difference: fraction of an
oscillation between the
vibrations of two oscillating
particles.
1.4 Angular frequency: the rate of change
of an angle expressed in radians per
second.
2 Requirements of SHM
2.1 A mass that oscillates
2.2 A position where the mass
is in equilibrium
2.3 A restoring force that acts to return
the mass to its original position,
where f is proportional to x.
3 Simple Harmonic Motion: when
-acceleration of a body is
proportional to its displacement
from the equilib position, when
they are both directed towards
the equilib position.
4 Damped oscillations:
when the ampliude of an
oscillation descrease as
friction transfers its
energy to its
surroundings.
5 Resonance: force mostion of
an oscillator, characterised by
maximum amplitude when
forcing frequency is equal to
the natural frequency
5.1 A system in resonance :
5.1.1 Has a natural
frequency to that of the
driver
5.1.2 Amplitude is max
5.1.3 Absorbs greatest
possible energy from the
driver.
