contributor: AAS Frey.Katie
alternative label: Acceleration of gravity
broader: Planetary science
definition: The rate at which a small object in free fall near the surface of a body is accelerated by the gravitational force of the body: g = GM / R^2, where G is the gravitational constant, and M and R are the mass and radius of the object. The surface gravity of Earth is equal to 980 cm s^-2.
