gravitational potential energy, the energy possessed by objects (especially celestial bodies) in the gravitational field is called gravitational potential energy. in physics, infinity is often defined as the zero potential energy point of gravitational potential energy. the expression of gravitational potential energy is e=-gmm/r. is a scalar quantity, the unit is joule (j). g is the gravitational constant, m is the mass of the object that generates the gravitational field (central celestial body), m is the mass of the research object, and r is the distance between the two centers of mass. the well-known gravitational potential energy is the expression of gravitational potential energy under special circumstances.

gravitational potential energy = −(g×m) / x

G = 6.674 × 10^-11 N(m/kg)²

m = mass

x = distance
