The gravitational potential at a point in a gravitational field is the work done per unit mass that would have to be done by some externally applied force to bring a massive object to that point from some defined position of zero potential, usually infinity . ... The two definitions are equivalent.

Equations. Gravitational potential energy at large distances is directly proportional to the masses and inversely proportional to the distance between them. The gravitational potential energy increases as r increases.
53292
The general expression for gravitational potential energy arises from the law of gravity and is equal to the work done against gravity to bring a mass to a given point in space. ... The gravitational potential energy near a planet is then negative, since gravity does positive work as the mass approaches.

Gravitational Force means the force of attraction between any two masses. Weight is the Gravitational force with which the Earth attracts the masses towards its center. Gravity is related to the resultant force with which a mass is attracted to Earth.

The gravitational constant, symbolized G , is a physical constant that appears in the equation for Newton's law of gravitation. ... The value of G in this equation is approximately equal to 6.67 x 10 -11 newton meters squared per kilogram squared (N x m 2 x kg -2 ).

Another approach is to consider "g" to be the measure of the intensity of the gravity field in Newtons/kg at your location. You can view the weight as a measure of the mass in kg times the intensity of the gravity field, 9.8 Newtons/kg under standard conditions.

noun Physics. a law stating that any two masses attract each other with a force equal to a constant (called the gravitational constant) multiplied by the product of the two masses and divided by the square of the distance between them.

1. gravitational theory - (physics) the theory that any two particles of matter attract one another with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Newton's theory of gravitation, theory of gravitation, theory of gravity.

Gravitational force is an attractive force that apperas between any two masses. Gravitational force is a force which means that it changes the motion of an object. ... Gravitational potential energy is the amount of energy a mass [apple] possesses due to its positions in the gravitational field.

The force of gravity is the force objects in space exerts on all other objects and is proportional to both the product of their respective masses and the square of the distance between them. The acceleration of gravity, you are actually supposed to put it as the “acceleration due to gravity”.

Work done against gravity in lifting an object becomes potential energy of the object-Earth system. The change in gravitational potential energy, ΔPEg, is ΔPEg = mgh, with h being the increase in height and g the acceleration due to gravity.

The center of gravity (CG) of an object is the point at which weight is evenly dispersed and all sides are in balance. A human's center of gravity can change as he takes on different positions, but in many other objects, it's a fixed location.

Gravitational contraction. The process in which gravity causes an object to contract, thereby converting gravitational potential energy into thermal energy. Gravitational equilibrium. A state of balance in which the force of gravity pulling inward is precisely counteracted by pressure pushing outward.

Gravity is a general term dealing with the whole topic. Gravitational field strength is the force experienced by a unit mass. Gravitational force is the amount of force acting on a body. It is the product of field strength times the mass under consideration.
