In astrophysics, dynamical friction or Chandrasekhar friction, sometimes called gravitational drag, is loss of momentum and kinetic energy of moving bodies...

Types of friction include dry, fluid, lubricated, skin, and internal. Friction can have dramatic consequences, as illustrated by the use of friction created...

processes such as relaxation, mass segregation, tidal forces, and dynamical friction that influence the trajectories of the system's members. There are...

cluster mass, of the total baryon mass within 12.5 virial radii. Dynamical friction is believed to play an important role in the formation of cD galaxies...

Tribology is the science and engineering of understanding friction, lubrication and wear phenomena for interacting surfaces in relative motion. It is highly...

pre-Newtonian explanations of the causes of the motions of the stars and planets. Dynamical time scale Ephemeris is a compilation of positions of naturally occurring...

mathematical modeling of the dynamic behavior of systems and designing them, usually using feedback signals, so that their dynamic behavior is desirable (stable...

mechanisms which absorb energy from the orbital motion, such as fluid friction, gravitational anomalies, or electromagnetic effects. For bodies in low...

resistance to motion. These two categories of friction are respectively termed static friction and dynamic friction. It is a force which is applied to an object...
