Gravitational Potential is:

Gravitational Potential is negative, scalar quantity, unit JKg-1. It is represented by the symbol V.

  • The gravitational potential at a point in a gravitational field is the work done per unit mass that some externally applied force would have to be done to bring a massive object to that point from some defined position of zero potential, usual infinity.
  • If the field is due to an isolated massive point object (or any object of finite size), then it is conventional to define the potential to be zero at an infinite distance from the object; the potential is negative everywhere else because the gravitational force is always attractive.
  • The gravitational potential energy is negative because trying to do the opposite of gravity wants positive energy.
