Gradient of gravitational potential

WebScalar potential is not determined by the vector field alone: indeed, the gradient of a function is unaffected if a constant is added to it. If V is defined in terms of the line integral, the ambiguity of V reflects the freedom in the choice of the reference point r 0. Altitude as gravitational potential energy The gravitational potential V at a distance x from a point mass of mass M can be defined as the work W that needs to be done by an external agent to bring a unit mass in from infinity to that point: The gravitational field, and thus the acceleration of a small body in the space around the massive object, is the … See more In classical mechanics, the gravitational potential at a point in space is equal to the work (energy transferred) per unit mass that would be needed to move an object to that point from a fixed reference point. It is analogous to … See more The gravitational potential (V) at a location is the gravitational potential energy (U) at that location per unit mass: where m is the mass of the object.
