> potential energy surface of gravitation extends in 1/r

What does this mean? Gravity falloff is 1/r^2 right?

[T-A]

Gravitational attraction falls off as 1 / r^2; potential energy falls off as 1 / r. The former (a force) is the derivative of the latter.

GP may have used superscript that got stripped, here's a test with normal numbers followed by the superscript version : 0⁰ 1¹ 2²
