0222 · The gravitational force formula is also known as Newton's law of gravitation Also, it defines the magnitude of the force between two objects Furthermore, the gravitation force formula includes the gravitational constant whose value is G = 667 imes 10^ {11} N cdot m^ {2}/ kg^ {2} What is the three laws of gravity?Joseph Priest, in Encyclopedia of Energy, 04 61 Gravitational Potential Energy The gravitational force on a box of mass m is mg, where g is the acceleration due to the gravitational force If the box is raised a height h, the work done by gravity is W=−mghThe change in potential energy of the box is then Δ U = − W conservative = mghThe positive sign means that the · The upward force required while moving at a constant velocity is equal to the weight, m g, of an object, so the work done in lifting it through a height h is the product m g h Thus, when accounting only for mass, gravity, and altitude, the equation is (571) U = m g h where U is the potential energy of the
