At which point is the potential energy maximum?
Similarly one may ask, at what point is the kinetic energy at a maximum?
At an object's maximum height, kinetic energy is zero/ maximum while the potential energy is zero/ maximum. 3. At an object's lowest point, kinetic energy is zero/ maximum while potential energy is zero / maximum.
Hereof, what is the maximum value of potential energy?
it can be used to describe the potential energy in a system of point charges (or radially symmetric spheres) as a function of their separation distance r, then the maximum value is zero at infinite separation. Hence, its maximum value is zero at infinity.
Gravitational potential energy U is V*m, that means it also depends on the mass of the orbiting body. So earth's potential energy is much greater than the potential energy of a comet far beyond the orbit of Neptune. The Gravitational PE is maximum at infinity and comically this maximum is a zero.
