- SI unit of gravitational potential is joule/kg.
So, its CGS unit is erg/gram. - All the planets move in elliptical orbits with
the sun situated at one of the foci of the ellipse,
according to Kepler’s 1st law of planetory
motion (law of orbits). - The product of gravitational potential and
mass of the body gives gravitational potential
energy. - The value of G was given by scientist Henry
Cavendish in 1798. - Graviton is the hypothetical particle that is
supposed to be mediating the gravitational
interaction, which is the weakest interaction of
all the four fundamental forces.
