Damping & Resonance Pop Quiz

NAME :

The amplitude of oscillation of the simple pendulum will gradually decrease and become zero when the oscillation stops. The decrease in amplitude of an oscillating system is called damping.An oscillating system experiences damping when its energy is drained out as heat energy.External damping - the __________ of energy to overcome _________________ of air resistanceInternal damping - the loss of energy due to the _______________ and compression of the molecules in the systemDamping in an oscillating system causesThe _______________________________The _______________________________To enable the oscillating system to go on continuously, an external force must be applied to the system. The external force supplies energy to the system. Such a motion is called __________________________The frequency of a system which oscillate freely without the action of an external force is called ______________________Resonance occurs when the system is made to _____________ at a frequency equivalent to its ____________________ by an external force. The resonating system oscillate at its maximum displacement.Resonance can be demonstrated with a Bartons pendulumAnswer this question base on diagram of Bartons PendulumWhen the pendulum B oscillate, all other pendulums are ____________ to oscillate.It is found that the pendulum A/B/C/D/E oscillate with the largest ___________________.Pendulum A/B/C/D/E resonatesThe natural frequency of a simple pendulum depends on the ____________ of the pendulum.Therefore, pendulum B causes pendulum A/B/C/D/E to oscillate at its ____________
