Why does field strength follow the inverse square law but potential does not?
Either in a gravitational or electrical field, let's say an electrical field, the electrical field strength follows the inverse square law. This is fairly intuitive just due to the geometry of the ...

Intuitive explanation that mechanical energy is conserved in gravitational field
Suppose you have $n$ particles with masses $m_1, \cdots, m_n$ with position vectors $\vec{r_1}, \cdots, \vec{r_n}$. Now without any forces except gravity acting on them, conservation of mechanical ...
