Dynamical friction — is a term in astrophysics related to loss of momentum and kinetic energy of moving bodies through a gravitational interaction with surrounding matter in space. It is sometimes referred to as gravitational drag, and was first discussed in detail… … Wikipedia
Constant-velocity joint — Rzeppa six ball CV joint Constant velocity joints (aka homokinetic or CV joints) allow a drive shaft to transmit power through a variable angle, at constant rotational speed, without an appreciable increase in friction or play. They are mainly… … Wikipedia
Coefficient of friction — The coefficient of friction is a dimensionless quantity symbolized by the Greek letter μ and is used to approximate the force of friction. Friction can be viewed, again as an approximation, as being of two primary types, static or kinetic . The… … Wikipedia
Fanning friction factor — The Fanning friction factor is a dimensionless number used in fluid flow calculations. It is related to the Shear stress at the wall as:: au = frac{ f ho v^2}{2}where:* au is the shear stress at the wall *f is the Fanning friction factor of the… … Wikipedia
Escape velocity — In physics, escape velocity is the speed where the kinetic energy of an object is equal to the magnitude of its gravitational potential energy, as calculated by the equation,:U g = frac{ Gm 1m 2}{r}.It is commonly described as the speed needed to … Wikipedia
Perrin friction factors — In hydrodynamics, the Perrin friction factors are multiplicative adjustments to the translational and rotational friction of a rigid spheroid, relative to the corresponding frictions in spheres of the same volume. These friction factors were… … Wikipedia
Muzzle velocity — For the computer video game, see Muzzle Velocity (computer game). Muzzle velocity is the speed a projectile has at the moment it leaves the muzzle of the gun[1]. Muzzle velocities range from approximately 400 ft/s (120 m/s) to… … Wikipedia
