Work (physics) object. The presence of friction does not affect the work done on the object by its weight. The force of gravity exerted by a mass "M" on another mass "m" is given by where r is the position vector from "M" to "m". Let the mass "m" move at the velocity v then the work of gravity on this mass as it moves from position r("t") to r("t") is given by Notice that the position and velocity of the mass "m" are given by where e and e are the radial and tangential unit vectors directed relative to the vector
