You have 2 pendulums attached to the same peice of horizontal string. One pendulum has a large mass, the other is small. They are both of the same length. The large pendulum is released from an amplitude and so the small pendulum resonates. The rate of exponential decay of the large pendulum is much slower, than if it were a single pendulum connected to nothing else. How and Why is this so? Surely the rate of exponential decay of the large pendulum should be faster and the pendulum dampened, as when energy is transferred to the small mass pendulum, some is lost from the system as it is converted to heat?
