thumb|Diagramatic symbol used to represent a dashpot. A dashpot, also known as a damper, is a mechanical device that resists motion via viscous damping. The resulting force is proportional to the velocity, but acts in the opposite direction, slowing the motion and absorbing energy. Kinetic energy is converted to heat. It is commonly used in conjunction with a spring.
