Question

Quizplus · Accepted Answer

The energy dissipated by damping in a system where a block on a spring is subjected to an applied sinusoidal force and a damping force proportional to its velocity is supplied by the applied force. The damping converts the energy supplied by the external force into heat or other forms of energy, thus maintaining the motion of the system.
