(Also called effective gravity, virtual gravity.) For a rotating planet such as Earth the resultant of the force (per unit mass) due to gravity and the centrifugal force.
Apparent gravity is given by

where g is the force (per unit mass) due to gravitational attraction, Ω is the angular velocity of the planet, and r is the position vector relative to its center. Like g, g* depends only on position. Within the earth's atmosphere the magnitude of the centrifugal force is less than 0.03% of g.
