what is displacement in oscillations
the distance from equilibrium position
what is amplitude in oscillations
maximum displacement from equilibrium position
what is wavelength in oscillations
one complete cycle of the oscillation
what is period in oscillation
time taken for one complete cycle of an oscillation
two conditions for simple harmonic motion
acceleration is directly proportional to displacement
acceleration is in the opposite direction to displacement
formula for acceleration in oscillations
formula for displacement in s.h.m.
how does potential and kinetic energy differ in s.h.m.
at equilibrium, potential energy is 0 and kinetic energy is at maximum
at maximum displacement, kinetic energy is 0 and potential energy is maximum
formula for total energy in s.h.m
what causes damping
when there are resistive forces acting on it
graphs for light damping, critical damping and heavy damping
what is resonance
maximum amplitude of oscillations where driving frequency = natura frequency
why does amplitude of oscillations decrease with time
the resistive forces acting against the oscillation causes it to lose energy
