(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

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.
