SHM
- Key definitions
- Amplitude: max displacement from
equilib position
- Period: time for one
complete oscillation
- Phase difference: fraction of an
oscillation between the
vibrations of two oscillating
particles.
- Angular frequency: the rate of change
of an angle expressed in radians per
second.
- Amplitude: max displacement from
equilib position
- Requirements of SHM
- A mass that oscillates
- A position where the mass
is in equilibrium
- A restoring force that acts to return
the mass to its original position,
where f is proportional to x.
- A mass that oscillates
- 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.
- Damped oscillations:
when the ampliude of an
oscillation descrease as
friction transfers its
energy to its
surroundings.
- Resonance: force mostion of
an oscillator, characterised by
maximum amplitude when
forcing frequency is equal to
the natural frequency
- A system in resonance :
- Has a natural
frequency to that of the
driver
- Amplitude is max
- Absorbs greatest
possible energy from the
driver.
- Has a natural
frequency to that of the
driver
- A system in resonance :
