· As the object oscillates it will exchange kinetic energy
and potential energy.
· At the midpoint, kinetic energy will be highest and
potential energy lowest.
· At maximum displacement (the AMPLITUDE) potential
energy will be highest and kinetic energy lowest.
· The total amount of energy remains the same provided
no external forces act (eg: friction).
· A FREE OSCILLATION is one that never stops. It has no
driving force and is not affected by friction this never
· The RESTORING FORCE transfers energy between
kinetic & potential…read more
· The velocity/time graph is: the gradient of the displacement graph
· And the displacement graph translated to the left by /2
· The acceleration/time graph is: the gradient of the velocity graph
· The velocity graph translated to the left by /2
· And the displacement graph reflected in the x axis.…read more
· Damping is the REDUCTION IN AMPLITUDE of
an oscillation over time, usually due to energy
loses to the surroundings (e.g. from friction).
· The reduction in amplitude is EXPONENTIAL.
· CRITICAL DAMPING is when the amplitude is
reduced to zero straight away.
· The graph shows light damping.…read more
