gravitational field strength, gravitational force per unit mass, gravitational potential (at a point), work done in moving unit mass from infinity to that point, moment of intertia, a measure of an objects resistance to angular acceleration about a given axis, escape velocity, the minimum velocity required to allow a mass to escape a gravitational field to infinity, where the mass achieves zero kinetic energy and maximum (zero) potential energy, centripetal force, force required to maintain circular motion, conservative field (electric / gravitational), energy required to move a (charge / mass) between two points in a (electric / gravitational) field is independent of the path taken, equivalence principle, it is not possible to distinguish between the effects on an observer of a uniform gravitational field and of constant acceleration), geodesic, path with shortest distance between two points, Schwarzschild radius, distance from the centre of a black hole (singularity) to the event horizon.
