A damper oscillator is a type of mechanical oscillator that consists of a mass attached to a spring and a frictional or damping force. This system exhibits oscillatory motion due to the interplay between the restoring force of the spring and the damping force.
The amplitude of a damper oscillator decreases due to the damping force, which dissipates energy from the system. This energy loss leads to a decrease in the amplitude of the oscillatory motion over time.
The damping force is directly proportional to the velocity of the mass in a damper oscillator. This means that as the velocity increases, the damping force also increases, resulting in a greater loss of energy and a decrease in the amplitude of the oscillatory motion.
The amplitude of a damper oscillator decreases over time due to the continuous dissipation of energy by the damping force. Eventually, the amplitude will decrease to half of its original value and continue to decrease until the oscillations come to a stop.
The amplitude of a damper oscillator can be increased by reducing the amount of damping force acting on the system. This can be achieved by adjusting the design of the oscillator or by adding a supplemental force that counteracts the damping force.
