Dalam mekanika, gaya gesek internal dapat menjadi salah satu penyebab efek pengurangan energi tersebut. Bagi banyak sebab, gaya peredam Ff dapat dimodelkan sebagai sebanding dengan kecepatanv dari suatu objek:
In mechanics, the internal friction may be one of the causes of such damping effect. For many purposes the damping force Ff can be modeled as being proportional to the velocityv of the object:
Di mana c adalah koefisien peredam, dalma satuan newton-detik per meter.
