Gravitational Fields

Gravitational FieldsSign up

understand that a gravitational field is a region in which a mass experiences a force, and define field strength g = F/m · recall and use Newton's law of gravitation F = G m1 m2 / r^2 · derive and use g = GM/r^2 for the field due to a point mass · use gravitational potential phi = -GM/r for a radial field · analyse circular orbits and geostationary satellites using gravitation and circular motion
