 gravitational potential energy   کاروژ ِ توند ِ گرانشی   kâruž-e tavand-e gerânešiFr.: énergie potentielle gravitationnelle   1) The energy that an object possesses because of its position in a → gravitational field, especially an object near the surface of the Earth where the → gravitational acceleration can be assumed to be constant, at about 9.8 m s-2. 2) In a two body system. It is the amount of work done in bringing the mass m to the distance R from M: EP = -GMm/R, where G is the → gravitational constant. 3) For a uniform sphere. It is EP = -(3/5)GM2/R, where G is the gravitational constant and M is the mass contained in the sphere of radius R.→ gravitational; → potential; → energy. potential energy   کاروژ ِ توند   kâruž-e tavandFr.: énergie potentielle   Of a system, the work done in changing the system from some standard configuration to its present state. Thus, if a body of mass m is raised vertically through a height h, the work done, mgh, is the increase in potential energy.→ potential; → energy. potential energy curve   خم ِ کاروژ ِ توند   xam-e kâruž-e tavandFr.: courbe de l'energie potentielle   A plot that displays the → potential energy of a moving body as a function of its position. It is explained by the → conservation of energy and the conversion of potential energy into → kinetic energy and vice versa.→ potential; → energy; → curve.
