Oscillations
, ① Simple Harmonic Motion
·
An oscillation is a repeated motion about the object's equilibrium
position
·
An object experiencing simple harmonic motion is one which experiences a
force which acts towards the of
restoring equilibrium

,
Conditions required for SHM
1) Force and acceleration are
proportional to the object's displacement
from the equilibrium position
2) Acceleration and force are directed towards the equilibrium position .
